As an abstract, this is very nice. I particularly like the radiating lines from the bottom center. The green and the purple complement each other nicely as well. My only negatives are that I would have preferred a lighter green to match the brightness of the purple as well as more of it.
On a side note, I wish I could tell what it is that you are photographing. That is just my personal conflict with abstracts and sure to drive my crazy as I keep voting in this challenge. |
