I just started listening to no.3 which I have heard many times played by real orchestras.
Your rendering is outstandingly convincing! The performance is almost like a real orchestra. The expressions are so natural and the shaping is nearly perfect. Its amazing that you took such a complicated piece and did an excellent job of it. I canti imagine how much effort this must have taken you!
The only criticism I have is that the piano sounds a little 'boxed in'. I dont know how to express it but it feels a little tiny to me and not 'grand'.
Besides that, I occasionally hear the 'tinny' sound of strings which was discussed in other demos as a standard issue with samples.
But overall very impressive. Congrats on the great work.
