It's looking great. If you have it on it's own layer, you might play with lightening up the darkness just a bit so you can show off some of those trees you have out there. It's almost pitch black out there right now It's sort of a toss up of you going for realism or usefulness. I'm thinking that since you have those nice trees out there it wouldn't hurt to show them off. Depends on how it looks and you have to make the call.
