Flowers give you strong colour blocks and soft edges — pleasant to assemble and forgiving to look at for an hour. Mixed borders and wildflower meadows break into recognisable clumps you can build separately and join later. Single-bloom macro shots are the harder case, since a petal gradient can run for a dozen pieces without a single hard edge.
Work clump by clump. A mixed border breaks into small islands you can build independently and join at the end, which keeps progress visible. On a macro shot of a single bloom, ignore colour entirely once you are inside a petal and use the direction of the gradient instead — it runs one way and tells you which end you are at.
Difficulty: Easy to medium. Macro close-ups are harder than they look. Every picture here is graded automatically by how much its neighbouring pixels differ, rather than by subject — why that is the thing that matters.
