Looking really nice, a few points of crticism though. More geometry in the tea cup and saucer so it doesnt collapse so much. Also i would be tempted to use a HDRI image of a kitchen for example, to me it looks like a warehouse?? Also a very minor point, model the cup as a whole, rather than the handle seperatly. Other than that looks really good.
This is really nice Jut, my view though would be the detail in the sugar cubes, not sure what it needs but at the moment I reckon they look like plastic. Appart from that I like the rest :)
