Muddy and thin at the same time? Need a bit of help

Sounds great! but maybe need e Mastering to bring up all of it.
If you want I can do it for you, have some free time now over the holiday

This sample is only your MP3 I master.

Latest mix sounds much improved man. Definitely got a good groove too. Still missing some high end I think but not much.
