@Librarium: Thank-you! I'm flattered that you would compare my little silly drawings to someone who went to art school. I have actually never taken any art classes or gone to art school, although I want to. I'm in the process now of trying to find a reputable art school that won't have me in debt for 30 years! I have not done any commercial work, though I have been tempted to put myself out there. Unfortunately, I'm a huge pessimist when it comes to my artwork. :/
I checked out that image you were talking about--that would be pretty tough, but it could be a lot of fun, too. I've never done that many characters all in the same image, and you'd be surprised how difficult that actually is (making sure proportions and height are accurate and making them all on the same plane, etc).
@Tyoka: No, I only paint digitally (I sketch with pencil and paper and have done some charcoal and watercolor in the past, but not much). But I did not set my layers up correctly to be able to integrate a background easily. I can, of course. Just not easily. I just want to move on from it for now--it was a great learning experience and I may go back to it someday. Thank-you for your offer, too!
