Lots of potential here. Great melody; quite menacing. Love the bell.
Only thing I think would help the piece a fair bit would be a lower string section supporting what's already there. Some roaring basses. Dun- DunDUN ; dun- dunDUN.
I notice you used Action Strings. Hmm, with AS you could have well-developed melodies.
This is pretty cool composition! Might want to add some slight reverb to the instruments to give it a sense of space.
Please contact me if you would like to use this in a project. We can discuss the details.
