Sketch of the Week: Water tower

Shortly after I'd bought my car in 2013, I took a drive to the south end of town near the airport. I was thinking of drawing the planes there, but it was already getting dark, so I drew the water tower instead, since it wouldn't take as long.

Yes, I know the tower is crooked in the picture; we'll just say I was channeling a certain leaning tower in Pisa.
