Tip - speaking of sky - it's difficult, if not impossible, to rework a sky in watercolor and is best left to the unprofessionals. I put in a light yellow wet in wet wash - let it dry - and threw on the blue.
People I met - a man pulled up in his car and asked me if I do paintings. He told me his brother had recently died and he wanted a giant portrait done from a photo for his mom. I always feel kind of bad saying no but there's just too much pressure involved in commissioned pieces. Especially if they are for surviving loved ones.
