Overall I think its a great start. Composition and general feel of lighting is very nice.
I agree with the others that the background is off. It's a bit flat, and off perspective. I think I see what you are doing with the fill lights (the one on the left etc.) - you may want to make those emitters larger to diffuse their light and shadows more so they are less obvious.
IMO the shininess of the floor is fine - I have a re-finished 100 year old floor in my house that looks similar, so it's real enough. I think you've got that typical MW cyan/blue cast that's flattening out the shot overall and killing the potential colour vibrancy in the shot. A minor tweak would make the scene more inviting IMO.
Nice bit of work dude
