Thank you very much guys for your kind comments ^^
MonsterZero, yea, from that moment that was definitely Alien like theme, before that it was more like Prometheus like discovering style.
pulserifle187, thank you, yeah, I guess it wasn`t completely Prometheus style, caz I am still not experienced enough for approaching the very close style of Prometheus, and there was a limited amount of instruments to use, so I just tried to use them wisely.
Necronom 4, thanks very much dude ^^ Yeah, I also had the feel it would suit smth like exploring the derelict, maybe some lights and holograms too, but then they find smth strange and everyting turns off, and smth begins haunting them, u can actually hear the roar, not very alien like, but it could be a completely new creature. Then there is some intense and they get out safely, but what they find is the tomb of Engineers, or a ritualistic place, anyways, somehow related to Engineers. Actually at first I called this soundtrack "in the tomb".
