I did this painting over one of my dad's drawings.

When I was young we would share a page in a sketchbook and work together on a drawing, taking turns to add details. I owe my love of drawing and painting to him. My dad has such a funny and unique sense of humor and it comes through in his art. I have always admired his dedication to creating what he loves. Go show the old guy some love.
Love you dad.
