Ugh... I don't like this. I just can't do trees. I don't know why. I think in this case the trunk is a bit too thin or something? I don't know. You are supposed to be looking down on the tree from an angle, but it doesn't look like that at all... Ugh. I guess I should be trying to draw each individual leaf individually (or a clump of leaves) or something, rather than just having it as a green blob?
