I think you have great concepts with all of your walls, but you might need to work on the way you make the walls. I'm not really sure what program you use to make your walls and what tools you use, but why dont you try out this tutorial if you have photoshop ^-^ -> Vectoring tutorial
I see some jaggedy ness in your wallpaper, and I think if you use that tutorial it might help with that and also with the screaming and ripping out hair. lol
