You know how it is. Sometimes, you just feel like drawing the underside of a giant, long-necked dinosaur. We've all been there. It's OK.
Or would that be a sauropod from below? I dunno. Sauropods aren't depicted from below often enough. They are so much fun for perspective sketches. I really love how giraffe-like these fool-things are.
