I found this cool illustration by Jose Manuel Rios on Behance today. I can't quite tell if it's been painted or created digitally and imposed onto a background. Either way it's a very easy to look at piece with nice use of colour and an intriguing expression. I think something should be said about the hair too, I find myself struggling with hair, whether I'm drawing it, extracting it, vectoring it or just trying to brush it hair is hard to deal with, and Jose has down a nice job here. Check out more of Jose's work here and an interesting blog here.
