Ringutubby poorly shaded

My brother likes pics like this but I couldn't find one of the green Teletubby (Dipsy, I think) getting Ringed, so here he is with Sadako! I'm aware there's lots of problems with the shading, anatomy, excuse for cloth, and so on but it was just meant to be a quick sketchy thing in the first place.
