Kinda messy on the left side... but the right side has some potential to add great flow to it. try taking out everything on the left side on the halo guy and adding c4d's or effects that go in the same direction as the right side. like this


sorry i had to reuse your c4d like 5 times to try and create a sense of flow.. it might not look good

you should try and keep it consistent.
Keep it up though
