Well this is an absolutely extraordinary and highly unusual portrait piece by Bristol-based artist Lee Ellis. I have not seen any of his work before, but that is because I think he is primarily a studio artist and not a street artist.
I took a look at his work on the Interweb and he has this incredible style that has a touch of menace and darkness about it, but also manages to convey emotions and passion in the subjects. It would be interesting to see what he could do with a proper outdoors wall. Striking work.
