Hi saw your post - might be too late. I live in LA o we have a lot of classes here. But did recently consider studying with Marla Kirban in NYC. She came highly recommended to me from someone who considers her his mentor. I took one class with her and it was excellent but for now I am using people who I can look in the eye. If you don't have that possibility then I would definitely recommend you call her or e-mail her studio. She is a former agent at ICM and I think that she could be an excellent contact if you are talented. If I find myself in NYC I will definitely take a private lesson with her.
