Beautiful composition, wonderful expression even though you don't see the eyes. I agree with the previous comment about the brim being darkened. I like the bohek of the background. Spot healing with the healing brush in photoshop on the skin and hat would take this to the next level in excellance. Well done!
her mouth is so provacative...her face is wonderfully highlighted, can't help but being a bit distracted by the highlights on her hat, they look nice, but draw me out of the shot...that is being a bit picky yes, but I tend to only get that way with shots I am drawn toward...
I like this a lot. Great composition and mysterious look with the hat covering her eyes. The only minor thing that I dont care for is perhaps a little too much texture in her lips.
