Hey, this is an interesting sound. I would really work with that bell sound and bring out out more. You don't need to have it play all the way through a song to make a main theme though. (Think of it as a chorus). For the pads, I would try to use some stereo separation next time (it would make them sound very spacy, which would be fitting for this song). On the other hand, I think you could use some improvement for the beats, but those take a lot of work. One thing I would try to work on right away is the base and the type of energy you are looking to put out (here the beats actually made the song feel slower (the beginning is amazing :))). You could try to make some drumstep, if that's what you're into. I think it would fit well with the song. Anyway, I hope this helps!
