One of the artists I find most interesting is Banksy - the UK graffiti artist. His work has a wry sense of humour that sets it apart from most other graffiti artists and indeed a lot of "conventional" artists. Do I actually like graffiti? That's a difficult one. The problem with graffiti is it's very intrusive and although there are doubtless many talented artists involved with graffiti there are also a lot of unskilled morons scrawling nonsense and generally reducing the quality of life for people living in urban areas.
Anyway - on with the design. Ironically, after spending hours creating a lovely clean design using the pen tool I went back in and dirtied it up, adding the shadows and harsh lighting effect that Banksy employs, mainly with paint bucket and eraser tool.
