Awesome singing pose with a great display of color. The blacks look great. I might add a bit of canvas on the right, and I'd try desaturating the reds/oranges a couple of clicks to see if it enhances color detail.
One of the nicest RWBBs I've seen lately, love the wings, clean BG, catch light and of course, the singing. This would have been a good candidate for video if you had upgraded :)
Awesome pose and BG here, Mike. The outstretched wings and open beak really make this on special. I do think you could bring out a bit more details in the red and yellow, although the blacks looks great.
Someone needs to tell this guy he needs a pedicure.
