For the OoT, one.
Yep the Bass is way over power, and whatever instrument comes in second sound very cheesy, or "not confident enough". I would layer that with something or widen it, something has to be done.
what is it you are going for exactly?
Will the final one be much longer?
Already stated but clean up the bass, I may even boost around 62Hz for more power but from 250-400 probably tone that down as well as pinpoint the hum pretty directly and eliminate that as much as possible.
In terms of composition it fares decently, except the length. Execution of the playing could be spruced up as well.
Good start and good luck!
