Nice drawings, guys.
Ugh, I like your Tony Stark. Face is lookin' like the real Robert Downey Jr.
MattAY, nice drawings of your characters. What do you plan on doing with your story?
And Ugh, use MSPaint, it's a good starting point honestly. If you can't use Photoshop, Paint is a way to go, although there is a program called "GIMP" - it's similar to Photoshop, but it's free, in the legal way too.
