So the question is...do I prefer one? Do others prefer a particular style? Where should I invest my time and effort?
And of course there is a third alternative, which is to make a more careful painting by choosing to do a pencil underdrawing that gets all the proportions just so, and on watercolor paper instead of in a sketchbook. Again, where should the effort be placed?
