The ground texturing work, rocks, etc. from foreground to background is excellent. Reminds me of the Scottish Highlands (or pics I've seen, at least). I think if you want that brown track to look like a trail of some kind, you should try to figure out how to flatten it a bit relative to the terrain, because to my eye it doesn't really read as "path" right now. Other suggestions for the abbey may be on target, but I really like the scene overall already.
