Not sure why you converted it to B&W when the tiger's color are so vibrant.
Because of the horrible mistake of leaving my camera at 3200 Iso... :-/ Caused alot of red, and any increase in saturation to bring out his colors better only worsened the red iso pixels. Oh well.. B&W seemed to have hurt me in this one.. Maybe next time.
Wow. This close I would have loved to see it in color with a little looser crop. You got a great expression/moment and the focus is good. Not sure why you converted it to B&W when the tiger's color are so vibrant. Good luck in the challenge!
