Deathcoreish mix I'm working on (need pointers)

[A Midnight Requiem]

This is the first mix I've done for this project, and I was hoping to get some constructive criticism/advice. It will be the first time my work is distributed to any type of retail store (from a very small independent record label), so this is a big opportunity for me! Any help is greatly appreciated, thanks!

It's quiet because it will be sent to a separate individual for mastering.
