I really like the positioning of the Urchin, and the contrast is great, one thing I feel could improve the image is a bit more depth of field, I think the focus falls off too quickly in the upper right area, but overall, very good.
oooo i like this. i'm guessing the purist crowd won't favor this shot as not "still life" but i think the b&w treatment here is awesome and i like the unique choice of subject 7
