Aquaspot-- Thanks for the tips on the moss grooming, and I'll be sure to keep you updated.
House-- Ooh. Thank, now I think I understand. Since these sticks are free to move, I'll try playing with them more as the moss on them grows in. I think the main problem is finding places for the R. Najenshan. Continuing the trees of course give a continuous to the forest, but finding the right spots for the R. Najenshan "highlights" is difficult. What I might do is (as the moss thickens out) try moving some sticks into the areas you mentioned and instead of moving R Najenshan, just allow them to mix-- that'd probably give a more realistic impression anyway.
