Hey, I've just listened to your track!
I really liked the instrumentation. However, I agree with the other feedback you've received: there are a lot of ideas introduced in a short amount of time. I think the piece would benefit from introducing them more gradually and giving each one a bit more room to breathe.
This would create stronger contrast, especially in terms of energy, and would allow your melodies to develop more naturally. If you're concerned about the length, keep in mind that 1:45 is still quite short for an end credits theme, so you have some room to expand.
Good luck with the rest of the voting period!
