nice simple idea - would have cleaned up background on right side (reflective) and maybe 3 or 5 jars (prefer odd number when they are similar in shape ; )
The main thing that got me is the reflections in the lids...you can tell your background doesn't completely surround the items, have to be careful when shooting reflective stuff, also some bright white between the bottles. I do like that all the items aren't at the same level or straight across, gives it more of a real feel. your lighing seems right on but contrast may be just a little flat. Good luck.
oooh i like this, jars lined in in straight lines. everything in the photo is so even until you get to the stuff inside the jars. interesting. and i like how you put that bright orance stuff in there... really stands out from the light colours
