Just my opinion.

I believe you have enough for someone to know if they want to work with you.
Having been involved in agency work I would have to say that alot of your stuff wouldn't be usable in a port. The artist shadow shots tell nothing much. I do see diversity in posing and also you have a great physique. I would mix in some straight out commercial looking images. Jeans and open shirt. Boxers in a bathroom setting or on a sofa..etc..Just my 2 cents..
