A wonderful image. Its minor drawback is soft focus as the eyes approach the steel grinders. Nevertheless, it remains a strong visual with lovely sepia. Bumping up.
Nice subject, nice lighting, nice tones. Unfortunately, the image seems to have been executed somewhat hastily -- the gap or shadow at the lower edge of the backdrop is distracting, and it seems rather under-sharpened for web viewing.
Composition: 8, Might use additional prop for more interest, pencil etc.
Technical: 8, Like sepia, but a bit dark in shadowed areas. Blends in with BG too much.
Appeal: 6
Challenge: 10
Overall Calculated Average Score: 8
Way better than my take on this :) Great use of dualtones and dof, lighting is great (high marks for use of a pencil sharpener -- and I thought I was being original!)
