Althought the colors are nice and the idea is on target for the challenge, this is just a bit un-interesting. The glass balls appear over sharpened and the light is very harsh. I hope that is helpful, and not hurtful. Good luck in the challenge.
This is a really good idea! For me, it was maybe cropped a little tight. But what bothers me most here is the brightness and contrast. Both are too high and instead of helping the photo, it's distracting. SCORE: 5 Well done and good luck!
Very hard light. This hurt my eyes. It seems to be opened with curves or brightness. Then the overexposure onthe balls are noticeable faster. There are a bit of a strange tones here too over the green balls.
