Simply beautiful!
I particularly love the expression on her face and the sheen of the water on her fingers and lips.
Now, looking at the other reviews, one could nitpick about proportions, scaling and foreshortening all they want. But there are so many finer details on this painting that really catch my eye, the picture overall just works perfectly, and I refuse to make any such comment. Without sounding cheesy, it feels like you've embued this work with its own spirit and given it a life of its own.
In particular, I admire the fact that in going with the theme of the seven deadly sins, you could have gone with something a bit more sultry or just flat-out inappropriate. But you've created something more here.
This one is definitely going into my Favorites. 5/5, 10/10!
