Looked through some of my old sketchbooks from last year. I may not think that I've improved that much, but oh how those drawings were not up to par. I do like the free form of some of those drawings though, not as restricted as I feel some of my drawing are, but you have to have the support beams before you can put on the wallpaper. I dunno, I guess I'm trying to sound clever, but I just have to master proportions, weight, squash and stretch, etc.. before I can really work on too much style.
Anyways ... Squirrel!
