THat is soo great! Yes, of course, the first impression is Hitchcock!
When enlarged, my eyes were cought immediately by that guy in the middle looks like screaming! THe motion blur and even some passants just highlight the dramatic effect! (If you were able to post this set means you have escaped the horror! I am glad)
Very intersting composition..
been there and witnessed this crazy bird chaos of course it all started by feeding them. Love to look at the faces and expressions of people in your photo. Catching a close-up face or two with a bird would been very funny
