So, let me get this straight. You sent in an audition ,then a couple of weeks later you asked for feedback??????? If that's the case, how could your agent even remember what you did?? If you want feedback, ask immediately. When you submit your read, either call your agent or write a note in an email that you'd love to get some feedback on this read. But a couple of weeks later???!! Heck, I don't remember what I read 2 hours ago this morning!!
Question: Why did you want feedback??? Did you think your read sucked? Was it a category you've not had much experience in?
Agents want to know their talent is confident and competitive. It's actually that confidence in your read and demeanor that they find attractive, and encourages them to work harder for you. I'm in agreement with Bobbin in that a coach or teacher would be a better person to ask. That said, your agent should be available to communication.
Instead of, "What did you think of my read?" I'd approach your agent with, "What can I be doing to take my career to the next level?" This gives your agent the opportunity to tell you if he or she thinks your recent reads need work. It also shows you are willing to take your career by the reigns and run with it. Many agents get frustrated with clients who think now that they have representation they can coast. Your agent will be impressed at your proactive approach.
It's the confidence that wins em over! Not just agents, but producers, casting directors, ad execs, etc. Be it in your read or your marketing. One of the many reasons celebrities work so much in VO is they are so confident with who they are, it comes through in their read. They don't need the gig. They just know how to be themselves. And it's who they are that the buyers want. It's their brand. They are confident in their brand. JUST like the non celebrity needs to be!!!!!!!!!!
