Here are a couple of recent life paintings of female models.
I often elect for a rear view study, especially if I don't have a long time with the pose. That means I don't get involved with the business of attempting a likeness and can concentrate instead on describing the form, the skin tones and the way light falls on the body.
I also like that the anonymous rear view is more evocative of womanhood generally than of a specific individual.
The prone study above (which I set) was the cause of a certain amount of debate about where the boundaries might be perceived to be between eroticism, sensuality and titilation.
My position is that I am not happy with the idea of boundaries in the first place, and that a good life painting can work on many levels, eg as an artist's practice piece, a portrait, an exploration of the human condition, and even as a kind of up market pin-up.
I don't think that we should be coy about the fact that we are working with naked human beings, and that sexuality is an issue, but for myself, I am probably most pleased when we have a model who's looks or shape do not conform to any conventional notion of beauty.
