Tracing with a Wacom tablet

I bought a Wacom Bamboo Touch recently and after a little rigmarole, I got it working. So I was playing with it and drew this. I don’t think it’s particularly good or anything. I just wanted to see what kind of stuff could be done with the tablet. I imported a photograph that I took and drew the outline with the pencil tool. I traced around the glasses, then around the lenses, and then I cut the lenses out with Path -> Difference. I filled that with black. Everything was very squiggly. I used Path -> Simplify to smooth a lot of it out. Then I used the calligraphy tool to color it, with varying colors and opacities. Most of the time I arranged the colors below the original outline, but I left some of them on top. I didn’t really think about it too much. I guess one thing I could have done to make sure the outlines stayed on top would be to put them on a separate layer. I duplicated the whole thing and filled it completely with black, blurred it by 5.0 and offset it for the drop shadow over a radial gradient background.
