This is for Jason who asked to see some work in progress shots from the previous post. You can see how much changed along the way; the skirt colour, jacket buttons, eyes open/closed, even the overall composition. Weirdly, the red bench in the background was the last thing I added. I work pretty organically - there's no science involved, not even by way of the colours ...but you're right, I naturally lean towards the warmer shades. I'm a great fan of warm browns and greys - you should see my wardrobe!
