I’d suggest not playing stuff like Satie to a metronome. I had a listen to your Gnossienne and the tempo seems pretty rigid. I think this kind of music needs to be freed from a DAW grid. If your Gymnopedie was also played to the grid, I’d guess that could have been a reason for rejection since a rigid tempo wouldn’t allow the kind of expressive phrasing that the piece needs to really shine.
Obviously, this is just my opinion and I’m just guessing, but I hope that helps.
