I cant tell if the grain is in your subject matter of the image so no knock there, I find the subject rather dull, but you got some lovely tones off it and the framing and lighting were very well handled.
nice lighting, interesting use of grain, nice angle. i'm not a big fan of focusing complety on another piece of art, but i'm getting a lot of drama from this object, i'm sure that took some work
The picture appears very flat. Perhaps if the background were of a different color than the subject, it would have shown better depth. Nice lighting though.
