Here's hoping this doesn't look as amateur as I fear it does. I tried like crazy to make all the edges right, but some didn't work.
Overall concept inspired by Epyongart's "Survey Corps" >> www.teepublic.com/t-shirt/56076-survey-corps

I want to put this on TeePublic, even if I'm the only who gets it.
