I like the light and the color you achieved here. The lens flare is a nice touch. I kinda wish it actually dulled the image more. It's a common technique used in fashion and it looks great when done well.
What I didn't like about this is her pose and your POV. It's too static, IMO. Her arms (one showing and one not) brings attention to this and since the one showing is pressed a bit to her body it sort of makes that arm wider rather than thinner. Also, her clothes don't really wow. They look nice but photographically they are not a stand out and they could have shaped her body better but that has more to do with the pose than anything else.
That said, her hair is wonderfully captured! The only thing that I'd touch up is the hair hanging over her arm especially since it seems to fade in and out due to the light hitting it or maybe you did some fixing in that area? Anyway, just some thoughts. If you didn't want a critique then just ignore. I do think it was a good shot and one of the more fashion faithful entries.
This image has great color, focus, and light. While she's well-styled, there are almost too many competing textures and colors. I think that the sunburst is a little over the top. The reflection in her sunglasses is very nice.
She sure has! This is a really strong photo, up against some strong competition this week though. I've scored 3 photos higher than this, and another half dozen the same as this - so by that reckoning I'm putting you in the top 10. Good luck!
