I tried some different things in this. Normally I try to stick with one type of brush(the standard round, which is really limiting but I feel for some reason that I need to try to be able to do everything with it), but I used a few different ones here.
I wasn't too sure how the shadow would work with the energy as the light source. The rubble/rock wall is questionable in spots. I normally do grayscale first but this time I blocked in actual colours.
I really wasn't too sure how I wanted to show the energy blast and just picked a colour that I thought would look good. I think it's normally yellow/gold but was green in one story.
Thanks! I want to try again as I'm trying to develop a more realistic style, but I think a realistic looking Thanos might look a little odd, like I thought he did in Avengers (it was still awesome though!).
