Acrylic painting on a crappy package board

An experiment made with the acrylic a day that I wasn't able to sleep. I don't remember how or why, but I saw a picture of batman that inspired me in a way...I couldn't stop until it was finished...at 3:30 a.m. It's nothing fancy, I used the only three colour I had: blue, black and white on a crappy piece of packaging board (the brown on the mouth comes from the board) and I think one brush...and a strange excitement.

(I've also fixed it a little with photoshop to make it more appealing on the screen)

I still don't know why I like it so much.

Have you ever had that feeling?
