Incredible, buddy! You're always so thorough with your work.
Great percussion, as always. I enjoyed the rhythm at 1:59, very catchy.
Im not too sure about the solo clarinet beginning at 3:32. This part is kind of flat, in my opinion. Maybe if you were to play around with the dynamics it might help. In fact, I felt the entire piece itself was lacking in dynamic changes in the non-percussive instruments. For example I felt at 1:59 the whole orchestra should have swelled and not just the percussion section. Bring those horns to the front man!
Again at 2:26, perhaps the strings, I feel, should be more noticable than they currently are.
I was really hoping that the little part at the end (starting at 4:14) had developed more. Haha. Maybe in another piece...
