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 :)
