try using more substantial effects and higher quality renders, and avoid over blurring
i had this bad tendency for a while and consistently produced low quality sigs too

i dun like your render choices which is almost as important as the fx ><
the lighting is als really odd, try using linear dodge with a gray brush on low opacity for your final lighting layer

The quality is killing me, mostly. They're pretty chaotic too. Hard to find any form of flow in the tag. Dunno, at this stage cnc is hard...just do tutorials like your life depends on it.
