My wife found this piece of driftwood and thought it might be fun. After she started she decided it was too much for her (which is wrong because she's already better than I'll ever be) so I decided to give it a shot. It occurred to me that if one looks at it right, ie: the mouth on the lower left, it looks king of like a whale. The shadow is different because my light source changed. In fact, the whole thing was moved because it was on the kitchen table and the space was needed.
