I like it. I think it works with the video nicely. Honestly though, I'm having a hard time connecting it to Vangelis' work. His sound is so unique and soul penetrating I think maybe the music could be more dramatic - I don't know just rambling now. I can hear some layered stuff on top of what you're doing to thicken it up maybe? (Still rambling ). A good try at a Vangelis-like tune though (was that what your goal was?) just maybe needs more elaboration.
Keep going with it. I'd love to hear it evolve more. And of course feel free to crit my stuff harshly also if you felt I just did (because it feels like that to me,
) - just speaking honestly so you can improve.
