I like the background since it makes good use of brushes but to have such a big sig with the stock image and text so little its just kinda meh... I know you'd prolly want to keep the sprite so I'd suggest making the sig itself a LOT smaller so the viewer's eyes arn't wandering all over the background only to randomly come across a sprite and text that isnt remotely close to the sprite. I know you tried to bring emphasis to the sprite by bringing light behind it (thumbs up to that idea tho) it kinda emphasizes really how small that sprite is compared to the vastness of the background. Keep working on it though, you got the artistic ideas right but your scale is what's really throwing it off.
