Well, isn't he?
One of the things I find interesting is how peoples body language changes according to how they dress - in this case, the horns brought out a playful side.
They are red, of course, and covered in glitter - another interesting texture to paint. Overall this painting will be fairly neutral in the background and coat, with much more highly coloured face - and the horns.
Another one I am interested to see how it turns out as it will be challenging - and I hope it meets the approval of the very obliging model!.
