Colorful characters you have here. Only thing is with your desaturation I feel without it being a true b/w desaturation, it works against what you're trying to accomplish. Try a true b/w desat, with a vignette to help eliminate border clutter and see if the image is stronger.
Ha! It's like flamingoes on parade. Lots of interesting elements in this. I like the back of the guy's head between the two "birds." Like the curvy thing extending off the left (but don't be surprised if some folks think it looks like a tail). Like the shadows. Good job!
