I used to be really into surrealism, Picasso and Dali in particular. My love for Dali has waned as I found out more about him, due to my inability to separate artist and art, so here's a well-known Picasso picture.
I'm aware that I'll get no hipster points for posting something so well known, but I still really like this. The colours (or lack thereof), the broken geometry, the symbolism - there are few better static depictions of the chaos of war.
Now I'm more of an impressionism fan, so I like the pictures that Crispy and Shadow have posted. As for drawing myself, I'm passable but not great (in particular I'm rubbish at depicting motion), and I can't use a tablet to save my life.
