Even thought you yourself think its not good, I don't.
If we keep the graphics aside for a minute, then the wallpaper is a perfect one to be kept as a desktop background.
I really am not of those type who like to keep fancy wallpapers with bright colors.
The wallpaper you have made is of the category which looks classy to me.
If I was an Inzy fan, it would surely have been my desktop background.
