I took a small hog brush and some black thinned with turps, and made these corrections. I'm ready for a cup of coffee now. I think I've nailed him. The trick now is not to loose him again in the re-painting.
An hour of frustration, then I squinted and obliterated all detail with blocks of tone. I'm finding that using a brush for each shade keeps me making decisions. I need to stop 'drawing' and keep on 'painting' if that makes sense?
