Here's how I draw basically anything. Wanna see? [thread] Step 1 : Unrecognizable, random flurry of lines. Step 1 : Recognizable element introduced (usually a facial feature).

It's not the best practice, but sometimes I'll just draw a part and "solve" a thing based on what's already down. Everyone has their own way of doing this, but I'll share mine. The thing's got a pretty strong vector to it [as indicated by the black arrows]. I also made a couple connection points [you could call them bridges -- red arrows]. My next move will make use of these things.
