I like the perch Sid. The bird seems a little soft, and would benefit from a tad more USM. Lighting is nice, and there is good detail in the breast. A slight head turn would be nice to let us see more of the eye. Thanks for posting!
Fully agree with comments. This particular pose is not the most attractive for little birds. I don't like seeing part of one eye, much rather have only one visible. Always a slight turn will get you a better image both from aesthetic and technical point !!
Generally speaking, birds faces head-on aren't that photogenic - (-: I don't mind this view but some may. I think this one is nicely composed with very nice detail. I think I would try to tone down the whites in the background on this one - the ones on each side really are blown. Overall, nice image.
