I'm unsure if I have a specific style when it comes to signatures it depends on what theme I'm going with before I head in one direction sometimes I head in too many directions for even myself to keep up with on certain signatures
Usually i use grunge, but i also use abstract sometimes. My current Sig(The FFX one) would be considered abstract i guess. I guess usually i use an abstract style for "happier" things, and i use grunge for more dark, gloomy and evil types of sigs.
I have to show my love for FFX
