Not one of your best. I like the clarity and the "expression", but the composition isn't all that appealing. There's a lot of blank uninteresting wall. Most troublesome is the dark "halo" behind the bird and the oversharpening.
6 - Yes I do. Just not crazy on the composition, empty space, slight grain/noise and background color. Title typo is a little detracting as well, but minor - unless it is intentional (if so, apologies).
Pretty bird. You did a good job of keeping his (her?) face in focus which is really important to me. I think this photo would have worked better for me with softer lighting and a different background.
There seem to be some issues in post processing on this image - there is a dark border around the bird that detracts and the blown out section to the left of the eye could be toned back some
