Sweet singing pose! Exposure work is solid and just ss to freeze that bill....nice!
Your posting of a 102kb size file is possibly causing some posteriztion in the background in what
would otherwise appear to be smooth bokeh...There looks to be a little photoshoppery mishap
by the end of the tail of the bird and the end of the perch moving up the right hand side of the frame...
some odd smearing....?
A couple of issues pointed out already, but otherwise a strong and fun image! Nice perky pose, details. I'd double the current amount of space between the lowest toe and the bottom edge...just feels a bit tight there.
I tried to rectify a couple of those but wasn't able to clear off the smudges at all places. I see it fine in PS and then when I upload it I start seeing it.. :(
