Cool Detailed Pendant Designs for Men's and Women's Necklaces and Bracelets

I just started a Jewelry Business selling bracelets and necklaces, and I have 3 Pendants I need Designed to eventually be 3D printed and then casted in copper and silver.
I need:
1. A Tree Pendant
2. An Eagle Pendant
3. A Lightning Bolt Pendant
I will need several more pendants designed in the future so I am hoping to find someone through this contest to work with again in the future. I am looking for some nice detail and craftsmanship in these pendants to sell as high end jewelry.

1. Tree Pendant.
*I want a nicely detailed Tree with Maple Leaves inside a circle (see attached Tree Pendant photos for reference) I like the style of the pictured pendant but I want a few changes. I've included some very rough sketch drawings too.
*Main Pendant: 38-40mm wide
*Main Pendant: 2-3mm thick
*Eyelet hole for chain to go through 3-4mm inside hole width. And I want the eyelet hole to be perpendicular to the main pendant. So you can see through the hole looking at the pendant sideways.
*Metal part of eyelet hole just 1mm thick
*The word LIFE in capital letters engraved on the side edge of the pendant. I am willing to adjust thickness of pendant if needed to fit the word LIFE on edge
*All I want on the back side (or underside of pendant) is my Logo design (the compass - not the name) Anywhere it will fit on the back side.
*Backside does not really need to have any detail except the logo. I am really only concerned with the details on the front.
*I would like the Tree to have some dimension and character to it. Not flat. I would like the maple leaves (see attached photo of maple leaves) to have some finely engraved veins if possible. And I would like the trunk of the tree to have a couple lines of texture engraved to look like bark. When these pendants are casted those little engraved marks turn black in the process and add a lot of character to the end product.
*I would like to be able to see through the pendant in spots like the sample picture I attached. I want the circle around the tree to be perfectly round and approximately 1mm thick looking at it from above.
*I will need 2 files created for 3D Printing each pendant. One for the necklace with just one eyelet hole at top. And one for the bracelet with an eyelet hole at top and bottom.

2. Eagle Pendant.
Nicely detailed flying American Bald Eagle Pendant (would like to replicate something just like the attached photo) The head of the eagle does not have to stand out like the pictured photo but if it is possible, I do like that style.
*Main Pendant: 40mm wide (from wingtip to wingtip)
*Same dimensions for eyelet hole as Tree above
*The word FREEDOM in all capital letters engraved on edge of pendant (top or bottom edge side of one of the wings)
*Logo on back like above (just the compass star wherever it will fit)
*I would like it as detailed as possible with engravings in the feathers and such. Looking for some fine craftsmanship here. I am not good at drawing but I have included some very rough sketches as well as other photos I like. Backside can be flat with just my logo.
*Again I need two files. The Necklace version should have the eyelet hole in the middle of the eagle. And the bracelet version need to have two holes put at the end of each wing.

3. Lightning Bolt Pendant
This one is a little more simple. I just want a clean "S"- shaped Lightning Bolt. And a 5 point star engraved in the center of the lightning bolt. I want it to be clean and sharp. If you have some other creative ideas, I am open to them for this lightning bolt. But I definitely want to keep it the "S" style.
*40mm tall
*Thick enough to write STRENGTH in all capital letter on upper left edge.
*Logo on back
*Eyelet hole same dimensions as above
*Eyelet hole on top for necklace.
*Eyelet hole on top and bottom for bracelet pendant.

Sorry, if this is overly detailed. I would just rather give too much information rather than not enough. Like I said, I have several more designs I will need to have made in the coming months.

Anything that looks cheap or cheesy. I want these to look as realistic as possible.

Yes

1. AutoCAD (latest)
2. I am unfamiliar with software. I just want something that can be sent to a 3D printer. The tutorial video said to say Auto Cad if I didn't know so that's why I put that.

My apologies. I said Eagle Pendant, but I want a Phoenix (Firebird) Pendant. I got my birds mixed up. I will be doing an Eagle in the future. I would like the Phoenix in the style of attached pictures. I want it to be very symmetrical and have wings spread flying upward. I would like it to have some details that will make it pop. But looking forward to see what you come up with. Thank you. - Tim

Important Update March 16

I posted this in the comments below but thought I should post it again here in case anyone didn't see these details. The are also a couple additional very important items of interested here:

*I want my logo (compass only) to fit on the back side of every pendant. I would like the logo to be debossed ("stamped" below the surface, but the star of the compass to be raised 3D like my logo appears). So my entire logo is below main surface but still is 3D. Hope that makes sense.
*I also want the words (LIFE for Tree, STRENGTH for Lightning Bolt, FREEDOM for Phoenix/Eagle) in all capital letters on each pendant to be written on the edge in the best placement possible.
*I want all edges to be rounded off. I think zulfadzryl did this in and Entry #4 but I can't tell if they are actually round or just beveled. I would like it to be rounded.
*Also each bracelet pendant (including the 2 eyelets) need to be EXACTLY 45mm with a 3.5mm hole opening for the eyelet. These measurements need to be exact. Nothing longer or shorter than this will work. I am using a 3mm leather rope and chain that have to fit through the eyelets. Necklace will obviously be shorter only having 1 eyelet (so 45mm minus the 2nd eyelet).

*We are opening this up to anyone who would like to try to design an Eagle instead of a Phoenix. We have not been totally pleased with the Phoenix entries so far.
*We are also opening up entries for Tree designs of any sort. It does not have to have Maple leaves - any leaf you choose. It also does not have to be in a ring if you do not choose. But all of our criteria directly above does still apply regarding dimensions and logo and the word LIFE.
*We are looking for pendant designs that are very detailed and creative. We have declined 95% of the entries so far because most of them were not creative enough or detailed enough or just did not fit the style we are looking for. We do appreciate your effort. Feel free to give it another shot with the Eagle and Tree.
*And please send us a link to a 3D animation of your design if you can. That helps tremendously.
