Accidental Scooby

My first digital painting with my new intuous5 tablet. I decided to draw a puppy and something interesting happened. I gave him a blue collar because I thought it would best complement his brownish fur. I then gave him spots to take care of empty space on his fur and add interest to his design. Only then did I realize that it looked like a puppy Scooby Doo. Perhaps there was more thought put into his design than I thought.
