I love the beautiful colors, and it looks like your lighting was great. A nicely done photo, but it lacks that "something extra" that would really make it jump out at me.
Beautiful colors, great composition and sharpness, and an excellent DOF. Love the bird's expression, too. If I *had* to pick a fault, I would say that the tip of the beak has a washed-out spot, but honestly, it doesn't bother me or detract from my overall impression of this photo. Good luck in the challenge!
A very vivid and bright image. Wonderful colors with good detail in the feathers. Considering the entire bird isnt in the shot a tighter crop may have worked better. The background looks nicely blurred but the beak and the shoulder are also a little OOF so just shifting the focus a tad or closing down the aperature a little more would have gotten more of the bird in focus. A very cheerful shot.
