I think I would have been tempted to remove the rag and move in much closer to include only the bottle, base and container to the left of it. That would have made a more interesting image for me.
A good effort though and a pleasing result.
This is a nice shot, I think it needs a bit more contrast and some dodging and burning. good seeing though, its a nice image. Just a little contrast and dodging and burning, and you could mount that and put it up in a show!
To my eye (and I'm just an amateur) this is a great photograph. Composition well balanced, good blacks and texture in the bright whites, with a good tonal range in between.
