This is a really cool effect using ordinary objects. The lighting is very nice. I'm wondering if this is actually 2 or one set up against a mirror? Good luck with the challenge!
very interesting study, good color and textures, slight asymmetry on the left where the outer arc is not filled in as it is on the right and colors are a bit different
Technical: fits the challenge well. Exposure composition focus lighting all excellent.
Personal: Sometimes a detail image like this one loses me because I can't tell what it is and therefore can't make any sort of emotional "attachment". But if it's well done then it stands on it's own as a great abstract. For me, this one is very well done. The colors and shapes are just killer. I'm looking forward to finding out what this was (and is it reflected in a mirror) when the challenge ends.
