There are some concept work for MMO "Afterworld" (http://www.afterworld.ru/) that I worked for a year ago.
This is post-apocalyptic Siberia setting.
I'm really impressed by the amount of design work put into this series. Each illustration shows a lot of consideration being given to details, and how the objects/environments would actually be used. It would be nice to see a greater dynamic range in the rendering style. In other words, more dramatic range of colors from the lightest light to the darkest dark. Some of the drawings have a great presence of character, but some are a bit monotone. I have the same problem. I will often try to show so much design information that the drawing loses a sense of mood.
Just another old dog learning new tricks.
