Mr sad is a character that I've made up.
Step 1: The Head
For mr sads head draw a circle using a compass and do smaller circles for the eyes, you want the eyes to be placed so its like a 45 degree view. You'll also want to put them a little low to make it cute and for or the mouth, draw a slightly curved line.
Step 2: The Body
For the body make him look a little plump. To do this make his belly curved. He doesn't have a neck so his arm touches his head and his legs are little stumps (kind of).
Step 3: The Arms
For his right arm it looks a little curved and he has no fingers. For his left arm it's just a curved line with a point at the end.
Step 4: Details
Mr sad wears a tiny top hat, a business uniform, a belt and a tie. He also carries a suit case. For facial details there is only the tears.
Step 5: Shading
Add small amounts of shading were you think it's appropriate
Step 6: Colouring
If you decide that you want to colour it in id keep his skin white and make his uniform grey and maybe only colour in his belt, tie and his suitcase to give it an effect
