Please help me understand what I'm doing wrong.

Your link to the track does not work.

Still does not work.

Good track! I like it. The only thing I would add more variety in the instruments, because by before 1:06 the monotonous melody on the guitar is a bit annoying and nothing changes in the instrumentation except the drums. And after the pit too. Moment 0:34 I would have done earlier at 0:18, the introduction is a bit long. That’s all I noticed, good luck!
