Cartoonish modeling...

I’m trying to model a cartoonish man, not a realistic one.
So I made the body from a box (subdivided twice and then used “To Sphere” and twiked it a little bit). but i’m having trouble adding the arms and legs…
Do you have any tutorials for this?

Take sides of the box and extrude them with the E key.

Yeah… I know… but it didn’t seem right.
anyway, in the end i used cylinders for arms and extruded only the legs.
