To give my characters better balance and weight I developed a tiny motorpunkish machine and placed it safely underground right under their feet.

All jesting aside, it's a kind of "meta-help" to me. Like an invisible marionette puppet master who's drawing down the characters. The machine illustrates the gravitational pull. The characters get more contact with the ground and stand (to my mind) like trees do. This here is not actually a proper drawing technique but more a "meta-thinking" thing. Technique is not everything - good drawing is also a matter of "meta-control" and playing a little I guess. Have I confused you enough already?
By the by, there is a brilliant post about "thinking around the form" over at

Before I forget... shall I post the drawing and colouring process of this fat motorsuit here as well before I archive this piece? Interested?
Update: Here's the entire process from start to finish...

And this is where the inspiration and colours came from:
