Have you considered using models for those surrounding hills and the ground rocks? The textures on the high gradient slopes are a little stretched which can be eliminated using UVed models. I’m in the process of replacing the terrain in midnight for models and the results so far are pretty nice. http://www.battle-of-wolken.co.uk/images/ETMAP/blend_comparision.jpg (Excuse the darkness).
The map is looking pretty nice though even if don’t use them.
