Just a wheel, ...so far

so I began painting in photoshop again today, and this is what I have so far, it's a wheel with a 6 spoke rim. I'm not exactly sure what I'm going to put it on yet, possibly a racecar or some such thing I'm losing my ability to see straight currently so I'm going to take a rest. Seems I need a better tablet and steadier hand. Using photoshop like this is really more like painting than drawing, in either case, I need more practice.
