Visit Adam Chrobak's behance folio and you will find an amazing selection of illustrations that depict a slightly darker and more aggressive world than what we're used to. His work is strikingly original and overtly raw. I think rawness is the essence of his work, in both form and content. These 2 are for me, stand out pieces but most of his work is ahead of the majority of the pretty, overly polished and filtered work floating around the internet today. Check out his folio here and there's loads of great work on his site here.
