Though the top of the boss piece appears to blend into the background it is still discernible which I like a lot. The lighting is extremely good. I would normally chastize for the centering of the subject, but the composition get a plus for the angle of the light area....
Very nice colors, I like the soft touch. I think it would also look nice if the bottom surface was straight and when the whole way across the photo, rather than on the angle. What I like the most is the colors.. 7
I like the blue glow created in this image. I would have cropped closer to avoid the edge of the table in the bottom right corner. And maybe try a lower viewpoint so as not the emphase so much it is on a table.
