Painting doesnt need to be a long and drawn out process. you can block in, as i did on this one, in less than 20 minutes and with a little more time tweaking of the shapes, make them closer to reality, until youre satisfied with it. i tend to not fuss over the canvas and that keeps it very abbreviated. this is starting to be the hallmark of my smaller painting style. for better or worse.
the more i work on them the less passionate they look so i stop a little BEFORE i think i'm finished. try it a time or two and see if you dont like doing it this way too!
