So it's not technically an octopus on account account of it having only 4 tentacles but we'll put that down to artistic licence. This is a great tutorials for testing yourself on shading complex objects and seeing just how unimportant it is to get the shadows perfect when you draw in this style.
I love using simple shapes to draw weird looking characters! This tutorials just uses D shapes and triangles to help get started and hardly any black lines to keep it light and fresh.
