I really like the shading on this, particularly with the subsurface scattering on the feathers: it really helps the whole piece "pop" in a nice way!The clouds also lend a nice, soft gradation of complementing colors, helping to frame the picture without distracting from the main focus.Some minor criticism, though, on the facial structure: you've got the eyes separated too widely. I used to make a similar mistake myself, since I was unconsciously following the "one eye-width apart" rule of thumb, carried over from drawing human faces. When combined with not giving the eyes an indentation (the look like they don't have sockets), it can lead to the eyes "bugging out" quite a bit.The easiest fix for this is to simply shrink the bridge of the nose, but you can also get around the issue by making the head less spherical, and more of an ovoid.
