I love solo piano pieces, and I think they are really hard to pull off, good job man!
Also saw it was your 1st finished song, you should be proud, I wish I 1st finished song sounded this tight :D
You have some really cool dissonances at work in some sections and you really do bring out some intense parts even with a solo instrument.
Sounds good, maybe just widen it up a bit more
Good Job, take care :3
