This is one of those subjects that you could spend hours on, trying to get it correct. Since that is not my objective with these two-inch squares, I had a few relaxing minutes of concentration, getting into the zone and not worrying about the outcome. A few minutes of lower blood pressure.
It could go either way, couldn't it? If it's a difficult subject we can drive ourselves crazy trying to do it right - make it good enough. Then we raise our blood pressure and wear out our erasers. I think it all depends on the reason we're drawing - are we drawing for the fun of it, or do we really need a good rendering of the subject. One reason is just as valid as the other, but we seem to have to give ourselves permission to just draw for fun.
Forty-three degrees here right now! That is something like sixty degrees warmer than it was a few days ago!!!
