Very nice indeed! The entire thing looks very natural.
You call it a tile, so does this mean you're planning a modular board with more of these tiles? If so, how do you plan to fit them together, seeing as your hills are on the edges? And what material did you use for the leaf litter on the left?
The second tile will attach to the grass side of the board, adding a board to a hill side wouldn't be that difficult as the hills final shape is made with B=Q filler as per the examples shown on this board (I lurk and I study.)
The leaf litter was old tea leaves (proper ones) crushed up with the twig bits left in as well as mixed herbs and parsley. the dark soil underneath is just woodland scenics fine turf soil.
The road is mig pigment dark mud over the top of woodland scenics fine turf soil.
Thanks guys
