Lovely composition, I like this abstract angle a lot. However, seems the attention is on the linen rather than the glass because it is what is most in focus, not the rim of the glass.
Great color, Im a big fan of abstracts, all this shot needs is to have the focal point moved to the edge of the glass. Thats the first point I look at in the shot. I love your use of shallow DOF, I just think the main focus point needs to be closer to the middle of the pic on the glass. Shifting the focal point and keeping the same DOF, this shot would be super slick. :)
Not a particularly bad image, but the almost complete lack of contrast in color kind of detracts from the overall quality for me. It's like someone put green cellophane in front of the actual photograph. If the fabric were a different color, even white or cream, it would be much more dramatic.
The use of the textured cloth really goes well with the shiny glass. Nice composition, too. DOF seems a little shallow and focused on the cloth rather than the glass.
