They look much better

If you haven't merged the lines with the green, they might look even better if the black/dark green is just a tad less contrasty with the lighter parts... I think. At the moment there's far more contrast in the pine needle texture than there is between the tiles on the roofs and the cracks between them, or in the thickness of the lines defining each of the stones of the ruined walls. Maybe use a mixture of oranges and not quite such dark greens instead of the black in those trees? (a dull orange like the cones and bark).

(If I'm getting annoying just slap me!)
