Love the composition! It is simple yet effective! Crop is as good as can be.
I like how there is a "rim" or backlight that is more prominently visible around the legs and side. It gives a 3D depth to the shot.
While your face is well lit, I think I would have liked it if your entire body was lit in the front as evenly as your face.
But perhaps this would have taken away from the rim light effect.
It might have highlighted the jewelry in your hand a bit more!
Due to the lack of light in the front, I think it created slightly muddy skin tones on your front arms.
Or maybe this is only more noticable because the face is well lit with a "warm" light of sorts -- which looks fantastic! <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
All in all, good picture! I'm just being overly picky here since you were asking for a critique! <img src="e.deviantart.net/emoticons/s/s…" width="15" height="15" alt="" title=" (Smile)"/>
