Red Dead Redemption II – The Uncut Albums – Feedback needed

I am currently in the process of remixing the entire RDR2 OST and I need some feedback regarding the mixing/arrangement/volume levels to make sure you guys get the best listening experience possible. I count at least 4-5 albums that I am currently compiling. While I am quite a headway through the arranging process, I need to know if I am on the right track with these medleys. My arrangements will feature music that has never been heard before and has in no way made it’s way to YouTube whatsoever (I know this for a fact).

Here is an example, I was just wondering if people could provide their thoughts on the arrangement. This particular track consists of 4 different themes blended together. I am aiming for OST quality with these mixes, so please let me know if I can improve anything.
