This is pretty cool!
I love your chord progressions, and they are very cinematic. I could definitely see the character of Dr. Strange within this piece. I don't know if you ever watch the show "Dexter" but the beginning had some moments which reminded me of the show's soundtrack (which is oftentimes eerie). That's a compliment by the way haha.
If you're looking for ways to improve, there are a couple of things you could do.
1. I think you rely too strongly upon the piano. There are some really nice pianistic moments in the piece, but overall I think choosing to use more other instruments more often could help improve the quality.
2. The piano itself has a bit too much delay on it for my liking, and makes the piano sound a bit cheesy.
3. I would have used a bit more percussion in your climax around 0:38 to give it a bit more power, with some nice heavy drums which you use in other parts of the song. Sustaining the brass at a loud dynamic could help as well.
Overall, this was really nice, I hope to see more from you soon!
Awesome.. Thanks for the advice. I'll keep that in mind on the next track I create. :-)
