I think you have really cool melodic and harmonic ideas, but your production quality doesn't quite match your harmonic and melodic creativity.
If anything, I think this could benefit from better quality samples, but I know not everyone has access to them on account of their price tag.
I really think you have great ideas, and maybe if you altered the velocities throughout your melodic ideas you would generate a more dynamic orchestration. Right now everything seems to be at a constant volume throughout, but more dynamic contrast could certainly add to it.
All in all, really nice ideas, just need a little work on the technical side. I look forward to seeing more of your work!
