sherm - looks nice, one thing i would point out tho is that those grays tend to be displayed with varying luminance form screen to screen. I use them a lot and find that sometimes they are the color i like, and sometimes (as your appears on my screen to be), much too bright.
here some art to pretend this thread is still fresh and alive:
quick studies form the Metropolitan Museum's nicely redone greek and roman galleries. granted they still dont have much (only one polykleitos and it's a roman marble copy), but it's nice.
Aphrodite i am happy with, hercules i probably should have doen properly (instead of separating into 3 values) and the shrunken legs (true to the statue by my measure) bother me as much in mine as they do in the original. oh well though, that's why we do studies of other artists.
