I'm not sure you can bring the horizon physically closer in Byrce. Try, though, playing with the haze settings. More or less haze should change the illusion of the horizon. You might also be able to change the illusion by either adding distant objects that will give you another "horizon" look--like a low line of mountains or trees. In the snow scene I did recently, I didn't want the infinite horizon either, so I turned the haze completely off and tilted my terrains up in the back just a bit, then put lots of trees in to help hide things. HTH! :o)
