I am still in the conceptualisation and early prototyping phase of a game that revolves around RPG/Bullet-time hybrid game where players compete in vs. style executing attack/defence moves per turn. 

I am in search for art material/guidance to have symbols representing moves.
For example a stick figure or a silhouette resembling a kick to represent a kick move. I am not really set on one specific style but would rather have something that covers a broad range of moves and be on the easy side to draw in not many strokes (yes player would draw the symbol).

Any guidance to get me started?
