I reckon it looks pretty sharp to me - very nice forests! I get that the rivers are stand-ins so looking forward to seeing how the finals look. Agree with rdanhenry that you'll want some of those flowing out to the ocean if you can. It's good stuff, though. Have some rep for getting the ball rolling!
