I call this series "Peeking" for obvious reasons. Oh and that's also the bad pun! 
This one's heavily cropped because otherwise it was just a shot of a fat, white, boring duck.
This one's heavily processed to bring the eye out of the dark shadow.
This one's not cropped at all.
This one is also not cropped and is self-explanatory.
All with the D100 and Sigma 80-400mm OS.
Hope you enjoy them.
