I was thinking the same as Forkie is expressing: this photo would have been a lot better, had the bird already flown far away enough to be outside the silhouettes of the branches. As it now is, the photo is very heavy on the left, with nothing there on the right - and the darker colours towards the right don't manage to outbalance the "leaning". Since I know how much you like to play with your colours, and how much you like to intensify them, I'll not say anything about those. The clipping of the reds may be the effect of downsizing the photo for web presentation?
