Painting Smooth Skin Is Not Easy

I painted this portrait of Bec, the wife of a friend of mine, for a recent live session on our Academy. Far out, smooth complexion is not easy, whilst trying your best to be painterly. Still - I think I got reasonably close to a likeness. Perhaps this is worth going a bit bigger though…hmmm. Quick question: What’s the most challenging part of portrait painting for you? #portraitpainting #oilpaintingtechniques #paintedfromlife #portraitstudy #realism #tischacademy
