+1 on the Van Gough . Was thinking Starry Night.
I love macro photography, but was never good at managing the depth of field. Always wanted to mess around with stacking macros for depth.
Would be interesting to up the grit on the sanding to get rid of the scratches. If I recall correctly, they usually only go to 600 or so. Would be neat to take it to about 2000. Since the finish is mineral oil, I'd think there would be little issue although I took my runt inspired knife's burl to 1200 and it's got a strange high pitched sound when you handle it gently.
