First I like that you captured the action of this bird poised to strike. However, compositionally, the angle from which it was taken in does not capture this bird or action in the best light. The angle was taken too much from an angle behind the bird with the results being that the bird's hind end is more visible AND (more importantly) that the action of the bird poised is broken up by the branch 'disconnecting' his head from his neck. A composition that is taken from an angle that shows the bird in side profile would not break up the action and show off the bird in a more flattering angle, especially the upstretched wings ready to take flight/pounce.
Technical: contrast could be a little more, the coloring and focus works well...the composition is good too!
Creativity: love the positioning of the bird...and what you have captured!
Score: 8
Composition: 6 - The rule of thirds is followed quite well here, but I feel the sticks need a bit of extra space around them to stop it looking cramped.
Technical: 4 - There are some blown out parts, especially on the stock, and the photo appears soft overall.
Creativity: 5 - Its not just the usual bird pose, which is good,
Appeal: 4 - The colours all seem a bit flat, and the blacks arent black, so the appeal isnt really tehre for me. Also, the head going behind the stick is distracting to me.
