I cant seem to keep my eyes off the background here. It is VERY distracting from a nice abstract. I would say a black background or something dark like black would be nice.
Very creative IMO. The use of reflections and shadows here are great. Not sure what was used as a background, but the texture in it, seems to pull my eye into the shadows. A flat BG might have made those shadows smooth which for me, wouldn't have pulled my eye so much. Again, just a thought. 7 for creativity alone with the shapes, shadows and reflections.
This would be great if the lighting was better. Unfortunately it looks drab and non interesting. Try it again but with better lighting. I bet it would turn out nice.
