Nice picture, i would have prefer the nest less in the middle horizontaly tho... In fact, I see that all the picture is going perfectly frame to match all the pipes equally, and I would have like more «disturbance» in the framing. Nevertheless, it still a very good capture.
I like this a lot. It would have been a little boring with just circles, but that nest creates a lovely contrast to the rigid circles and gives your photo a center of interest. Lovely blues too.
This is very cool. Did you put the nest there? If you did, it might have had a stronger impact if it were not quite so centered. Or you could have cropped this image differently.
