not baaaaaaad Dam! like you stated, lots o'polyg0nz used D: dont be affraid to add some stuff from the modifier stack - noise etc, you can push out those cliff face quads to form some nice defined rock faces aswell. Get some sharpness in the cliff formations aswell as some rounded sections near the tops (mix and match them :X)Updatessssssss!
So I decided to re-do the whole cliff, this time working on both the inner and outer parts at the same time to make things easier for me. This time it should include your suggestion, too, Muff. The polycount is pretty high for something like this, so I'll see what I can do about reducing it after I'm done with the first cliff. As for the bridge and trees, I'll be doing those last. I want each tree to be different, so that'll definitely be time consuming.
Also, if any of you guys have any ideas on a border (for the inner map limit), please let me know as I'm completely out of ideas.
oh and invest in SpeedTree
keep it up d00d
