Nice color range. A couple things though, the focus is somewhat sporadic, and the flash is a bit harsh. Did you try a longer shutter speed? Natural light might really pop these colors out.
Focus is off, tilted slightly, Each of these vases shows a nice curve. I think the shot would have been more effective if you would have chosen just one or two. It appears that green one is reflected in a mirror? Maybe try a shot of just that one with a reflection. The lighting is nice
I think this photo is too cluttered, and there doesn't seem to be any real point of focus. Focussing on one of the vases in front and having the colors blend in the background may have given a better effect
I like the lighting in this photo. The bottom right hand side is out of focus. If those bottles in the bottom right hand corner were'nt there it would be an awesome photo. :)
