I agree with what Flumen said about needing to be fuller and rounder - i.e., more punch. The drums especially are overly compressed and flat. The hi-hat has sound issues too - much too sibilant.
This is a great composition with a lot of potential if you get the sounds and mix better. Per Envato stipulations, you can resubmit but ONLY IF IT CHANGES THE TRACK SIGNIFICANTLY. Be sure to explain your improvements in the comments-to-the-reviewer-box. Good luck on the project!
