Alena

This is genuinely sultry, and there is a sense of power, intelligence, and character in the model's expression. Also, the hand, hair, and ring all complement each other.

Technically one could argue that there is a color cast here. But I've never understood why it's necessary to eliminate that, if it works for the feeling the photographer wants to convey, as I think it does here. That would be an interesting subject for discussion.

Very nice work!

Exceptional work. Congratulations.
