I didn't vote on your entry during the challenge, but I would have given it a 6. It is a bit too centered for me. Perhaps tilting it so the vine comes from one corner to the other could have improved the composition a little... and placing the circle a little off-center. Otherwise it is very nice and a good entry.
I gave it a 7. I like the linear qualities to this piece. It merely lacked an exceptional interest level. The title was no factor one way or the other.
Love the tight focus and composition. The subtle colors are refreshing too. Everytime I see one of these I wish that I could take a photograph that looks like this. Great work.
