My faves are #1 and #4, hands down.
BTW, you did a tremendous job with this subject - absolutely perfect.
My favorite subjects at the Philly Zoo are the Canvasback ducks. It's nearly impossible to get a good low angle on them with the way they have it set up but they're gorgeous, photogenic subjects, just the same. Just don't try to photograph them from mid June thru October, 'cause they're molting and it takes a few months for their new plumage to fully develop. January thru May is really the best time for them. I'm curious to know - did you photograph the Canvasbacks?
