Gorgeous background, great pose, and excellent exposure and detail !
Not too sure about the crop though. Maybe a bit off the top and right
to get a more rectangular crop with bird to the right side. Might work
nicely as a vertical as well.
Very nice work. This image has the technical qualities of a good image, maybe a few adjustments aesthetically would put it over the top. Either working a vertical composition (makes for a rather large crop, IMO) or as Fabs suggested, taking some space from the right and top.
