Pretty cool atmosphere, a bit dark souls like but toned down, I think its nice the first minute then we're stalling a bit. You can also add some EQ at some point to the percussions and transient to make it pop a little more if you want to create more tension later on instead of keeping it the same, you did it  at some point with the doublebass but I think it can be more in your face. But if we want to keep it ambiant it will need to be subtle. I think the overall mix can also probably get a little boost in dB. But thats pretty good overall , good job :)

Mandolin!!! I want more mandolin! Fantastic piece, perfectly fitting for an RPG, giving a sense of foreboding anticipation and ominous dark ambience. The thing which struck me as having more room for improvement were the repeated drums, needing maybe some work to make them sound more organic, and maybe centering more their panning (but that's maybe my headphones' problem), which were a tad heavy on the left ear because of the repetition. And the mandolin. Not because it was badly recorded, but because I want to hear MORE of it! Good job and welcome to the jam world!

Well done on a tight timeline! I will second what was said below: I would love to hear that Mandolin mixed up more in the forefront. It sounded great and I'd love to hear it more! I like the elements/instruments you worked with and it all seemed to fit well!
