This is awesome. I love the expression and the color. Maybe a little less "shine" on the face/nose/cheeks/forehead? I'm not sure how you'd do that exactly, but they distract slightly. Wonderful pose and composition.
I like the shot a lot. You have captured a great moment. My only advice would be to consider the vignetting again. I find it to be a little too strong for this image. (oh, and you might want to fix the typo in the title). Good luck this month.
