I had some time to spend on this last night, here is the result.

Next, i will try the suggested method for lights and shadows by Jacktannery from that Yuan-Ti thread. For now, i would be happier if the objects somehow stood out more. Do i do that with some shadows?

Also, i would need some advice for the cave entrance on the south, i have no idea how to make that nice. And also on the south eastern part of the caves, there supposed to be these natural steps down, but i don't know how to do that. As you see my attempt with some overlay didn't come out very nice

(As a side note, i removed the map from the first post as it was quite a big file. This one is smaller.)
