I thought as I said, your mp3 sounded excellent! But it sounded to me as if the orchestra was in a large hall, but the piano was added later, from a studioi. I'm fairly certain more reverb would make the piano sound as it it's also in the hall. I've listened to countless recordings of large orchestras and pianos, and I know I'm not an expert (that's why I'm on this forum!), but I do recognize the thing I just mentioned, because I'm trying to achieve that reality also.
I'm looking forward to tying your fxp, when you're ready to publish it, because I think it's very, very good! And frankly, I dodn't know why you're hesitating at all, because it's better than some others I've heard (including some of mine).
And thanks for the nice words about my piano!
