Planetary Empires: Old Shelled Tile

For this Planetary Empires tile, I've picked out the shelled portions in codex grey and washed them darker.  In the surrounding regions, a selection of browns and greens play out, suggestive of a once fertile but now abandoned region of the planet; accentuated by the old forgotten wall (top left).  This tile is unusual for me as I've added some static grass to the top right quadrant of the tile (brighter green).  Although it was a little bit of an experiment to see how it looked, I think the static grass has worked out very nicely.
