I'm an actor/singer who moves well... sometimes. I'm actually a great mover but not every style fits my body and a dance call back is my worst nightmare.
I have mentored two young aspiring actors and I wish that I had known I could look for a mentor because it would have been a lot easier to be able to ask those questions to someone who had gone through it already.
I can't say what my greatest strength between acting and singing is...I'll leave that to the critics. Maybe my best strength is performance itself, being with the audience and feeling what they feel, bouncing off of them.
