Hey there Brian, and welcome!
this is the list of photo suggestions from the 501st websire:
The following tips will help make sure that you get the right photos to the GML on your first try:
Only submit pictures of yourself alone against a plain background (no convention photos, please).
We will need photos with your helmet/mask on and off (if applicable).
You must include full-length views of your costume from the front, back and both sides.
Be sure to take your photos with adequate lighting and at a high-resolution to help us inspect the details.
Do not wear any non-canon accessories or add ons, including jewelery, glasses, earrings, (unit patches, extra weapons, pauldrons when not part of the canon costume etc...)
If you include any weapons such as a blaster or lightsaber, please ensure that they conform to the weapons policy.
