It's eating away at me

Yaaaaaaaaaaay finally posting something! Figured out how to use Krita (the art program I'm using) in such a way that the artwork came out decent, I had no idea you had to use large canvases in order to produce more quality works. However now I've discovered my computer can't handle larger canvases... There is adobe photoshop 7 or fireaplaca that I could use, both of which work smoother, but neither of them give me the right feeling or tools that I want.
