It's not really a sig, per se. It's more of a poster-ish kind of graphic. For your first attempt, I'd say this is okay. The black brush lines in the back are a huge distraction, though, and you didn't blend AJ Styles in with the color too well. The color of the text throws it off, and I think I see a hint of glow around AJ? For your first try, it's okay, but there's room for improvement, man.
