I have a new phone with Android and I simply needed to ponify it as much as I can. Finding a suitable wallpaper was a problem... then I suddenly found Pinkie breaking fourth wall (in this case PC screen) wallpaper... this was the perfect one! I just wanted different glass color and the original Pinkie was in low resolution, so I downloaded that dark glass wallpaper, erased the "hole" in it and traced a brand new Pinkie.
There is a similar wallpaper on dA: [link]
But I have not used it to make this piece.
Feel free to use it if you enjoy it
