Hand Drawn from a reference picture, then scanned into my computer. I brought it into Adobe Illustrator, where I penned over my pencil lines to create a clean outline, which I then colored in Photoshop!
Never will I ever even THINK of attempting to draw Arnold Schwarzenegger as Mr. Freeze, so don't bother asking.
NOTE: I forgot to add a highlight to Freeze's suit (the black part) - sorry.
