You were right when you said "Ha, ha" after asking us to go easy on you. This is one of your best pictures! It's the first time I've heard someone say they drew it on an iPad. Oh yeah, of course something as functional as that would let you draw on it. I think the best parts are the valley shown before the tree. It's like snow being plowed over.
Trees of life are pretty awesome. I even like the buildings to the right. I wish I knew what kind of buildings they were. I can just imagine what kind of story this tells. People should make entries based on art pieces.
