I'm having a go at this challenge, but I've hit a point of indecision. Typical.

(1) shows where the foliage and gravestones will be place, (2) shows the cut-off point for player movement, and (3) shows the general area of movement. Question - what sort of textures should I be going for concerning (3)? More grass, soil/dirt, a brick footpath, or something else?
Edit: I should add that the only things considered 'complete' in this picture are the gravestones and foliage. Everything else is expendable!
