I haven't hide time to go out and get a new sketchbook, so I've been finding unused areas in my current one. Normally I don't bother with this, I move onto a fresh page whenever I'm doodling so that I'm not encumbered by a lack of space, but I have to say I've gotten a few little gems using this approach. I guess the confined area affects my creativity positively. This dragon is only about 4 inches square, though he's not little by any means.
That's suppsoed to be his tail sticking out from under him, but it almost looks like he's sitting on another dragon. Nope, it's his tail.
