Great start, I can't help you with the renderer, never heard of it, but one thing I would say, lose the teapot, its too old fashioned as well as being MASSIVE!
Possibly think about adjusting your camera lower to an eye level shot too, its maybe a little high here? Around 1650mm off FFL should be about right? The blowing out of the white areas, as said above, also needs reducing as well as some re-working of the cooker hood material, its too basic at the moment. either add more modeling to it or substitute it for an extractor from the Google Warehouse.
