I like gear in game stalker, it combines technology and the old Soviet style of gear at same time. And I invented here small game for myself. I'm taking few parts of gear from items grid in game (vest, weapon and if needs a helmet) and drawing character that is wearing it. By this way I'm having fun like if I should really wear this gear and really feel it. For the backgrounds to not have much problems I just download screenshots with landscapes from game and using it also for making light on character. Light makes sketch more interesting as I think.
