Does anyone know of any quality composer's forums where music can one can look at other's music and have theirs looked at in return? I'm not having a lot of luck Google'ing the topic.
You should take a look at "Composer's Forum." A Garritan Forum member, Ron Ferguson ("Rolifer") is a moderator and very active composer there. He used to be more involved here at Garritan, but I hope he hasn't totally disappeared.
