Did this today.
Oh my god, I had a lot of fun doing this. Oddly, the hardest person to color the Human Torch. I can't seem to do certain elements without tutorials, but since his stuff was cartoony, I knew I can get away with certain things.
I colored this while my Photoshop is fouling up. It crashes when I select the type tool. Luckily, I still have the lovely Photoshop Elements and I didn't have problems with it ( to my knowledge.) but the big thing was I couldn't convert to CMYK which is the hot thing.
