'He's quiet,but knows all'

"He's like a cat, he's quiet, but knows all." ~~ Mayo
This is a Lux-Pain fan art that took me a week to finish mostly because of my cold and procrastination.
This was my first attempt at graffiti(which is why it looks bad )
EDIT: I spelled S"I"GMA wrong

Lux-Pain belongs to @Ignition
