The kick drum in the beginning in my opinion can use a low pass filter to cut off some of that high end. Just to make the kick drum have a little bit more of boom sound. The Snare and Clap are WAYYYY to thin. This can be achieved by layering, EQ, or compression (or all of them) and a overall slight volume increase. The piano is your lead instrument so it should cut through but not over power. I want to hear more of the dynamics of the piano is it will be the instrument to carry your whole song. Good song structure otherwise and keep it up![It all] sounds very thin
