Could the edge of the floor or table or base have been removed by moving the umbrellas back a bit so that you could crop it out? The only polish needed on a interesting and well executed shot.
Nice...good light, colour, composition. My only nipick is the edge at the bottom. I'd knock it out, personally. It's curved (might be pincushioning from the lens) and distracts. The scene would appear much more stable without it.
I don't like your use of harsh overhead lighting. I would have preferred softer, more diffused lighting which would have brought out the colors better too. Also, I don't think you should have shown the end of the table at the bottom of the image.
