first, I have to say I really like your wallpaper service, but I have a problem. My skin has the new 3px skin model and this is what happens this when I try to make a wallpaper.
As you can see, part of my arm is gray and my hand too, but with normal skins, it works.
To test it, you can use my skin. Just type ElFlima as the player.
P.S.: I am Spanish and maybe I write something strange. That’s because I’m still learning English.
P.P.S: This bug only appears if seen the part of the arm which is backwards the arm.
