ok... im gonna give you basic cnc just for guidelines.
when you put c4ds in a sig, you dont want them to take away from your focal or render.
They should be used to give flow and certain effects to your tag.
Look up "basics of a signature" on google and see what you can find tutorial wise
The things every tag should include are
Depth
lighting
composition
flow
even the best designers have trouble with these sometimes and take awhile to get down.
But your a beginner, so take your time on your tags and read up on some tutorials
