My kids bought this set last year for my wife. We never use it as regular mugs are always handy. Home studio with white sheet as backdrop. Two 100 watt bulbs and diffused on-camera flash for lighting. 50mm on zoom.
PP in Gimp
Crop Square
Select white backgound and use curves to make it stark white
Levels/Curves on the serving set
Dodge/Burn all some uneven tones on the lettering
USM

I think this is a nice product shot, even thoug your focus seems to be a bit off, you are showing nice detail of your product, wich is what most people like, specially if you are buying from the web or a catalogue.
Technical aspects: I think you did a good job with the background, and the composition is pleasing, though some people would have prefer a different angle, maybe positioning the camera at the same level as the mugs. The lighting is acceptable, but I think you can get a cleaner picture, one without reflections, it help if you can use a softbox, and some reflecting items, sometimes even need a double diffusion.
