This drawing was an attempt to illustrate a feeling that most parents are quite familiar with. A tiered parent and a kid who just wants to play. I think that the look of the big rhino and the smug smile of the cub says it all.
The original drawing is 100x70 and drawing with nothing but black ballpoint pen on grey recycled cardboard. It took me just over 40 hours and I used up 6 pens.
