I needed to see that knee. And to tousle his hair a bit.And define his obliques... and a host of other details that may change with each iteration. But I like having something to back into and rework a little bit at a time. I used to do tha to doodles I had next tot eh telephone back home in Manila. I would doodle something, and later on, another call, another day, I would doodles something else on it, or add to it, or develop it. I should have kept those phone calendars.
