I think this is a wonderful image and I like what you have done with it. You should be proud of this one!
I do believe it could take a bit more sharpening. Speaking PS and USM maybe something like setting of 94/0.4/1 and immediately Faded to Luminosity (Edit>Fade USM>Luminosity>OK)
Arsdel, great image - the Anna's are keeping these guys away from my feeders so far, so I admit my jealousy! Agree with Kim about the sharpening, and I would probably crop the image tighter top and bottom. Great capture, and the perch and background make it extra sweet. Thanks for sharing
