Just finished a set of rough character designs for a new product line for Battle Systems (www.battlesystems.co.uk). We intend to use these characters for box art, promo stuff and possible inclusion in a games system we may develop later on.
Each character has been designed with multiple games systems in mind so there's a little bit of Warhammer 40k, a bit of Space Hulk, a bit of Malifeux, etc. and influences include Fallout 3, Dieselpunk, Aliens.
Will do some more polished character concepts soon.
