Those are beautiful, mixed. You got some great moments of those birds. Did you have to wait for their beaks/bodies to get lined up so perfectly? Great job! Fantastic composition in the first picture, as well. Did you use a coloring effect on it? I can't quite tell if it's sepia-toned... (i think the fact that i have to ask is great, though)
One thing I might suggest: mess around with dimensions more. Crop some of those suckers. I might just be talking out of my ass, though... you're obviously more talented than me.
