I think the top one has a freshness about it, but I agree with Diapositivo; I'd like to see one bottle more clearly and the reflections in the right-hand bottle top are distracting. Perhaps you need a soft-box or a large, white reflector to eliminate these reflections. Half a stop more exposure would make those colours really glow.

The second one is about a stop under-exposed; I can hardly see the liquid or the product name. The dark background is nicely done and the cap reflection is a nice highlight. The reflections on the bottle's shoulders are again distracting; again I think you need a large white reflector or a soft-box. All IMO, of course.

P.S. I think there's a crtitque forum around here somewhere...
