May I ask a little review about a track?

Hey everyone,

My experience as author started few months ago and I was pretty much happy to see two of my works meeting the standards of the site. However, the rush to try on put more material on sale made me less focused on the quality that around 3 projects had been hard rejected.

So this made me returning more cautious on the production of new items and these days I was working on this “dark trailer soundtrack”.
It does still require a bit of mastering but I would like to know if structurally and regarding the mix down/ sounds/atmosphere it can be considered worth of been uploaded and, if it would be better to be uploaded as single track or, if could work that first part and second part might work as two standalone tracks, in the way they can be sold as a pack of two items?

here the sample

Thanks in advance :bowing_man:t2:
