A lovely image, a lovely model, a lovely smile.
A not so lovely square format. The watch isn't lovely also. The colours, get rid of them and convert this to black and white. Burn the background, so that I can see only the face and the smile. And, work on the title.
Maybe a too late comment, but this is the best from the photos on your front page. In my opinion.
Sweet model, and in a relaxed casual pose.
The cropping could be better though. I said that because her head seems suspended due to her not-so-visible arms, at first glance at least. Then again, still a nice portrait.
A nice pose and the lighting works for me. Being advanced editing I'd have tried to do something with the brown thing in the background to tone it down a bit. I'd maybe also have a bit more in the frame to the left - out to her elbow perhaps?
Lovely portrait, a little catch light in those beautiful eyes would draw more attention to them. Try fill flash or even just reflecting some light from a white foam board.
