Searching for Survivors

Finally I had time to watch =nukeation's great video tutorial [link] , which covers some good tricks about terrain function editing. I started to experiment with terrain functions, then I ended up making this snowy scene (because I very rarely make snowy scenes).
Though it's hard to see, this terrain is pretty large; actually it's 50 × 50 km large.......have you noticed the helicopter??

Thanks for viewing!
