/cgl/ - Cosplay & EGL

hello, first bag and first time posting here and I wanted to ask for some ideas / concrit!

I know I want to make a new insert that's bigger than the base bags default since theres a decent amount of space that could be filled, but i cant decide on a fabric color / print for it. should i just stick to plain white since the merch colors are a bit all over?
i'd also appreciate any concrit on the layout, if it helps i also have 3 more of the can badges on the bottom corners!
