I'm experimenting again. For this set, I wanted to do two things--get some hard grunge that I liked and challenge myself to use colors that I normally don't. So you have one here that looks like the Incredible Hulk, some grayscale, and a softer blue one because I felt like trying the grayscale ones as overlays. Zip file coming soon.
