I've started fooling with the water. So far, I'm pleased although it needs more contrast. Taking a photo while a painting's in progress is a great way to critique it. Better than turning it upside down or looking at it through a mirror. Viewing it on the computer monitor is really helpful...all the "ugly" areas that need changing jump out at me. Although you would love to be a fly on the wall when I walk into the studio the next day.
My reaction when I first see it: "ugh!".
The strength of criticism lies in the weakness of the thing criticized. - Henry Wadsworth Longfellow
