Level 1: Overall Tree Shape- Green bent triangle
Level 2: Tree trunk and branches structure, inside green shape
Level 3: Sub branches coming off horizontal branches
Level 4: Needles coming off sub-branches
Each of the levels is following the shape and direction - and line of action of the level above. Every detail fits within the overall scheme
