Thanks for the compliments, these are a lot of fun to work on.
I am indeed using HeroScape terrain. (It's a fun game, I've played more of the Marvel than the rest.) I have a green cutting board to set everything on and a navy blue foam core board for the background. I'm using a 7.0 megapixel digital camera with soft flash and "flower" setting (whatever that is). I've picked a few fonts from dafont.co so each character can have its own voice, and I throw it all together in Paint.net. Voila.
In frame 3, I just have him turned enough to turn his head, but so that his legs still look straight ahead...it turned out alright.
