very nice balance with the black values! The crop is perfect with the shape of the vase! Well done!!
The shadow adds an interesting 'still life' touch to the back wall. Not sure if it takes away from the overall iamge, but it helps the depth of the scene. The subtle tint in the floor is also helping... it's so easy to make this all b/w, and the difference in dark values pushes the white forward very well.
Well composed, and very sharp.
Working on a Tim Burton movie right now...and what's funny is, that's the first thing that crossed my mind when I saw the image!
