Excellent. Just excellent.
Your work in textures is so far beyond my skills that I cannot make any useful comments, except to say the mapping, interpolation, and resolution are perfect for the model. The label, the woodgrain, the steel look like real materials, which justifies the 10 hours you spent.
The geometries, meanwhile, are all nice and smooth; there are no "telltale" signs that its CG, and the object design is really nice. I actually applaud you for that dishtowel! Did you use a Wave modifier, or did you hand-model the folds with SubSurf modifier, or did you use another technique?
The one and only thing that I would give a 4/5 on is the lighting. It is *almost* there, but there are some strange things going on. For example, the wine glasses aren't casting a shadow on the countertop. Also the shadow of the wine bottle clearly shows that you have 3-4 lights arranged in a horizontal line; the light from a big window like that would cast one broad, soft shadow instead of those multiple shadows. The soft shadows looks perfect elsewhere, it's just on the wine bottle that the shadows are weird. The last lighting problem is that the apples, the wood of the window, and the glass vials (on the left) all seem to be lit from the front, while the drawers under the countertop are not. It makes the apples look a little like they are glowing compared to the bottom of the image (I would check Materials for the Emit setting on those apples).
I hope my comments were as constructive as you were looking for. Cheers!
