Marine Corps Birthday

I have a lot of friends and family who are associated with the Marine Corps for various reasons, so this year I decided to make them all "birthday" cards for the Marine Corps 233rd birthday.

I tried to make the cards look like the Marine Corps Dress Blues uniforms. I couldn't get some of the fine detailing done (couldn't find the supplies out here), but this is the end result.

I am interested in any advice on how to improve them, especially if you have suggestions on doing fine details like braiding, edging, etc.
