The tracks are good, but reviews are getting stricter.
Regarding the Epic track, the thing is that there are thousands and thousands of tracks that sound pretty much exactly the same. It would have to really stand out to make it, but I don’t feel this one does. The transitions at 0:30 and 1:43 are not to my liking. There is a very distracting beep in the right speaker that would take the focus away from any video it was used with.
Also, the ostinato is a bit harsh and unnatural for my taste.
The second track is cool, I like it! I don’t know if you did it already, but I would make a version without the vinyl noise and the breath sounds - it would make it more useful. You can still include the other version as an alternative.
Vinyl noises are cool, but imagine the track being used at low volume in a video with a voiceover. Those crackling sounds would stand out and it might not be really clear that it’s intentional.
