No. I used Paint Shop Pro. I drew the line art on paper first. Then I scanned it, and enhanced the line art in PSP. I CGed it from there, using the same program. ^_^
Aww that is such a kawaii pic! I love the background wow the colours are really beautiful and I like how you've smudged them together ^^
Agent proto looks great too I love how you did the face and hair and the sword is cool! And good job with the side view I usually have trouble drawing people from the side ^^
Good job on the face and hair. That hair really looks like Proto. The coat looks good except for the front of it I guess. You have a straight line from his t-shirt going straight into the coat. The coat should be sticking out there a little more instead of blending right in with the t-shirt.
