Sometimes when I have not drawn or painted anything for a while .. I think .. I'll just do a small sketch to keep my hand in. But these small sketches can be a bit frustrating as they are so small that they get a bit fiddly and small details are sometimes difficult to get right eg. the eyes!
Anyway, I think the treatment of this one is a bit Renoir-ish - I watched a show about him recently and some of it must have rubbed off on me. I like the colours here. From a reference photo but changed.
