Really good job dude! I would like to agree with the above about the drums. If you are not doing it already you should group all the drums to a subgroup and apply some overall compression. Another really good tool to use (with or combined with the compressor) is the Dcamp envelope shaper or Kongs transient shaper to tame those transients and make the drums sit even better together.
Really good enhancement of the mix otherwise, be proud of it!
