There may be some friendly sketches lurking somewhere in Michal Dziekan portfolio, but it seems like most of his work takes us to the darker side of things.
His art pieces usually compose of grotesque scenarios and portraits of fearsome characters. Some of the themes covered in his work appear range from human flaws, apocalyptic themes, and commentary on war. Although his illustrations may be disturbing, they're interesting interpretations of his creative mind. More pictures can be seen on his blog.
