Awesome! Love the expression, absolutely love the rich colors, and the DOF really brings the focus to her face. Perfect job on the vignette.
A fantastic portrait! Insta+fav!
As for the crop, I think it's great. I might have offset it a bit more left, or dead-center on her eyes. But I also like it as-is, because her hair gently balances the composition.
Nice shot! I know it was a fleeting moment so composition is harder, but it's just a little too centered and dead on... I'm thinking cropping it so that ther is more meg space on one side or the other would help. JMO
