DOOM - Concept Designs

Much of what you find here are retrospectives of the concepts as the thought process behind them was lost to time... Much of what I make stems from an initial idea which I remember by creating a name such as 'Eternal Demons', and calling upon that memory at a later date. Much of this is surprisingly improvised and generally magnatudes different to that initial thought. What you see here is what I best remember of an idea for the older concepts.
