It does look really good and clearly you have some artistic talent, I wonder then if it would look better with a backdrop that has a similar graphical style to the foreground terrain as the sharp contrast does stand out some ?
I should point out that the skybox and golfer model were made by Psionic, but I did everything else. It's a good point though, the realistic style of the skybox doesn't really match up with the other elements. Originally the terrain was going to be textured differently, more in keeping with the style of the skybox, but my plans didn't work out leading to the "style" we have now.
Having said that I think the terrain fits well with the golfer model so maybe I should look at changing the skybox...
Hmmmm... I've got several bits to work on this evening, but if I get 5 minutes I'll give it a whirl...

EDIT: Forgot to say that Psionic also made the trees!!
