Hi, I like the composition, it’s really great! But the mixing needs improvement! The balance of the different instruments doesn’t fit well, there is no punch behind the drums, while the piano sounds a bit too intrusive to me…

Mixing and mastering was bad, but the idea of nothing. work on the quality and succeed. Good luck.
