Magnificent
I just checked out the Monster Engine, and I must say your work is fantastically better than Dave DeVries'. Here's why.
DeVries starts with the kid's drawing and literally uses it as the outline for his. He takes the shape the kid creates and fills it in with nice realistic shading and applies backgrounds and such. It's little more than a parlor trick. He's going through the motions like he does in his job as an industrial artist, using little more creativity than some street artist drawing cartoony portraits of people.
But the kids don't know anything about perspective or proportion, so why would you count their drawings as an accurate idea of how these things they're imagining are shaped? I remember being a kid and not knowing the first thing about drawing something to really resemble an object from my imagination. You Newgrounds artists have used your own creativity and imagination to figure out what the kids might really have wanted to draw. DeVries looked at a kid's drawing. You looked at a kid's vision.
DeVries may have failed because, despite all his talk, he's forgotten how to really see through a child's eyes. You Newgrounds artists haven't forgotten at all.
