John Singer Sargent is quoted as saying, "Whenever I paint a portrait, I lose a friend." I think I know what he means. Of course, he painted most of his portraits in oils and could rework and change and make things right, over time. The only way we can do this in watercolor is gesso the watercolor paper first, then you can wipe back to white (or close to white).
So I took a painting of Mr. Forbes I had done a few years ago and wiped it back to white (apparently, I had spray sealed it with acrylic spray so had to use the Mr. Clean Magic Eraser to wipe it back but it worked just fine). Then began again, trying to work slowly and carefully, taking breaks and looking at the features.
What I see wrong - the white moustache and beard don't look right and I need to figure out how to do this without putting Chinese White on it. Perhaps a tiny brush to lift off anything that's white, leaving the color around it. What else I see wrong - I've made his face longer and thinner at the top than it is, plus I've taken years (decades?) off his age.
So, back to the drawing board for this one. I need to give it some time to rest and try again with little changes as I go. And get rid of that Chinese White moustache and beard!
