this is a strongly pattern-driven composition... have you considered B&W for it? The colors you chose work well together so it doesn't NEED the conversion, just wondering if you played with it.
Actually, I shot this at various exposures, with some + and - EV so I could test out the single-shot HDR in my software. This was a single shot RAW file that I split into 3 images, with +/- 2 EV, then combined with HDR blending. I was mostly interested in how well I could bring out the patterns in the wood fence, and the much darker details inside the window. I was happy with the result. I don't think anyone is really interested in a print of this subject. I will look at using a B&W output to see what it brings out . . .
