Practice. One of the reasons I enjoy drawing at the Drive-Ins. I have been creating caricatures for a few years now. I have had the pleasure of working next to some talented artists, and am following the work of many others. And its seeing their progression that motivates me to get out and practice.
I try to sketch a new shape, a new mouth form, and on this evening, some new forms for coloring. In the future I will post some of the demos that don't make it to the photos. Maybe I will link some of the artists whose style I am practicing. If you haven't already joined my online newletter group, I will begin sending out requests for models for my efforts to improve.
