Abstract Painting

I was frustrated, since I had both artists and writers block. So I painted this. I used a sponge and my fingers and was listening to Vocaloid at the time xD It is for sale, I've already had one person say that they might buy it, but they didn't tell me how much for. You can name a price, since I don't like putting a price on things...

EDIT: This is up for bidding on ebay! -> [link]
