I like the softer light in this Ken, which in turn has brought out the colours so well. I would take this any day, as you have captured him in the open nicely. Separated from the BG too.
Another special image of this shy species. I agree with Stuart and like the detail and exposure on the plumage also nice head position and eye contact. Great capture.
Background looks fine to me Ken. Wonderful pose, maybe a little tight in the LRC, but light's great as is the overall handling of the opportunity IMHO. :)
