Lovely shot and lovely bird
I think a wider aprature may have made him or parts of him at least, unsharp judging by the narrow DOF in the pic.
Its somtimes nice to see the habitat too. I would prob like to see a little less background in this particular pic too but as is
often the case its sometimes just not possable. It may be poss to blur the background in PS though
At the end of the day its what you like that matters
