I think the blur at the back of the image is OK, however, only the very front inch or so of the saucer is in focus. I'm curious as to (1) where the area of focus was, (2) what was the aperature. I would have extended the DOF to include from the front of the green saucer to the back edge of the yellow lip.
The direction of the lighting seems good, but the blown out window frame is distracting, as well as the bright piece of silverware in the left hand side. I also find the chopped-off hands of the person to be somewhat distracting as well.
Always think...what are you really trying to show? What object should be the most important visually? And what order to you want the objects to be viewed in? If you really want the coffe cup in the front to be the most important, then I would eliminate all other objects but the table, saucer, cup and wall behind.
If the focus is the feeling in the entire room, then maybe you would want to zoom out a little bit, and extend the DOF throughout the frame (f/22 or higher).
I think the overall colors and warm feeling was acheived nicely, and to me the most important thing to try and change would be the focus and DOF on the front cup. I always will shoot a variety of shots of each composition w/ varying aperature settings, so afterward, I can have my choice.
