Very intriguing piece. Really strong riff. I can think of nothing that would work better than this in a movie or cable show, especially a suspense movie, maybe even a horror film. If that's what you're aiming for, in my opinion, you're aiming in the right direction.
With an intriguing intro, the song progresses into several sections, each with a unique musical personality that adds to the ambiance and scope of this many-faceted composition. A lot of thoughts come to mind: dripping water, passing time, wonder, mystery, power. Nice job putting this together.
I liked how the beginning was intriguing, then I like how you built on the main theme.
