I honestly think that this is very good if looped, you should not add other stuff, I think it would fit well in some horror/thriller game. I see well a drum groove starting after some time, but that's it.
I really like this track. You really captured the feeling of suspense, although I find the noise-drone at the end a little bit too prominent. Since I imagine this song in a videogame like Deus Ex or Shadowrun, in an area where you are not allowed to be - a stealth mission sort of - then you would probably listen to this for quite a while and then this could be a bit distracting. I am talking about that drone-noise-pad that starts at 00:02, 0:12 and so forth. Other than that I think you really fulfilled your goal and I had no problems imagining this piece in a cyberpunk game/movie. Maybe a little bit more variation would be nice but since this is a WIP I think you will improve this. Other than that I can only say that from my perspective you are going in the right direction with this. Nice work :)
P.S.: While I am writing this I probably listened to the song for ~20 times and it is really not distracting but still keeps me sitting straight up in my chair. Good job!
Thanks a lot for the input! Yep, it is probably a bit repitative, but I was supposed to make a 20 second ambient track. I could not imagine how this would not be repitative ;) I´ll definitely have a look at the drone nois pad. The noise pad I added to sustain a bit suspense without using dissonant harmonies in general, because these would be a bit unnerving in a background loop. Maybe I should reduce the volume a bit if it is too distracting... It´s definitely good to hear that it works!
Please contact me if you would like to use this in a project. We can discuss the details.
