This is fantastic. A really solid demonstration on a good balance of cinematic / anthematic scoring with ambient work.
The only feedback I have is the drum stings near the end sound a bit blown in. Meaning their should have either their mids are really flat in the mix and it makes them sound a little distorted and saturated. Finding the right dynamic to shave off any clipping can be a super long process. Think of a limiter like an instant compression. Zero attack time, meaning zero room to wiggle around and work with any frequency changes that are going to effect the actual track / instrument. It won't go red or appear like it's clipping, but in the mix and to some ears it's going to come across as over the dB threshhold of the rest of the tracks, especially in ambient work and the creation of ambience. It's better to find a chain that allows you to maintain a high end so your mids don't entirely take over when compression tries to compensate by boosting mids to squish the low ends. It ends up creating a sort of opposite effect.
But this is fantastic, one of my favorites in the jam.
