Pretty little bird! Nice positioning in the frame. There is a lot of yellow/green in the branches which camouflages the bird a bit. I'd mess with reality and either desaturate the branches some or shift their hue toward red/orange to make him stand out more.
Excellent, you managed to avoid having branches in the way, that's a +1 for sure! I wish the bird would have been more interested in you, however, a wonderful image for this challenge.
