Recolour of previous art, made for a dear friend.
Gengar is known as the “Shadow Pokémon”, but what exactly is it a shadow of? Take a look at a picture of Clefable, and then one of Gengar. Their body shapes are almost exactly alike, with the only major difference being that Clefable has a curl for its hair and tail, while Gengar has spikes. However, the shadow of an upright spiral like Clefable’s tail would only be a line, or a spike.
