A good tip of advice when creating any sig
- Is don't have a character or item popping out of the sig unless you can actually make a normal sig effectively first.
- Keep your sigs small the more compact the better, this way you don't have to worry about filling the sig up.
- finally experiment this is the best option to do, Don't go and few all the tutorials and make a sig like everybody else with dozens of C4D and the same effect layers. They all end up looking bland you want a sig to stand out and be unique to you.
