is it any good?

Woah! that's pretty cool, it's kinda bright on the eyes though! GJ

that is very good for a first wallpaper, the text and render fit well with the bg and it all just flows together smoothly. Word of advice though, the type of wallpapers most people like to use are usually more abstract or landscapey type stuff, instead of wallpapers based on games, and shows. I'm just telling you that out of past experience.
