Here's a hand study I did last week. I was trying to prepare for a painting I've got to do where the sitter is under a red lamp so I the aim was to study the effect of the light on flesh tones. (there going to be in a bar too, hence the pint glass, sadly no beer)
The problem with painting your on hand is that you attached to it! I'm try step back a lot when I paint, but for this I was pretty restricted, still a fun exercise when there's no-one else to paint.
I've been painting this cast again, she's really hard! I find it very difficult to capture her expression, I think I must have scraped back the face at least four times. I'm really enjoying painting the casts, it’s a great way to practise for portraits and also really analyze tone.
