All right feedback time.
Percussions are killing the rest of the mix, way too present its almost all dead centered, you gotta pan those way more and balance the volume to let the melody intruments pass through, The tuba at the end is also way too loud. I think the composition is fine you got interesting ideas the mix is the big issue.
This might seem brutal so don,t try to be too offenfed, its still a nice track :)
