Why So Serious?

I'm a HUGE Batman fan, and love to draw the Caped Crusader, so -because I've nothing better to do - I've done a collection of pictures featuring the denizens of Gotham. Above is The Dark Knight himself, and over the coming days you can expect to see my favourite characters: Mr. Freeze, The Riddler, Commissioner Gordon and, of course, The Joker.
As ever let me know what you think of them. The pic above is meant to be simplistic - all shadows and darkness, just like Gotham and its 'hero', and its also meant to highlight just how alone Batman is.
