I had an idea to post these preliminary sketches for the above drawing - this has been a good method for me over the past few months, to work out several roughs, refer to them for a large loose pencil sketch, and then lay a clean sheet of drawing paper on top, tracing out the basic shapes and adding details based off the earlier sketches. Having three different roughs helps to choose what details are best to put it. Have one that is simple block shapes (since you want your drawing to communicate quickly) and the others with several variations of details. It's almost like having several reference photos and you assemble what you like best in the final piece.
