|Greetings from the Critique Club!
Wow, does this shot ever remind me of Magnumphotography...in a good way though! Great portrait, love the use of bokeh and thirds, lots of contrast and fantastic tones. Like the contrast of the curving neck vs that huge evil-looking bill. Looks like the light was quite high at the time, so good work on avoiding hard shadows and glare.
The only reason I can think of for this shot doing poorly, is partly due to the fact that FS is always tough, and simply that there isn't an unfortunate frog or fish in its bill, or in the act of being tossed down that gullet, with a decorative stream of water trailing behind it.
Hope this helps, keep shooting and enetering!
