Your preview level retiled in the style I prefer. Is this how you usually tile your cliffs? This style gives the diagonal cliffing a more fluid motion, as I said earlier, plus it gives you more options when you're detailing a level (you can make nooks and crannies along the side of the cliff easier, etc).
Also Crono and a few others dislike this style of cliffing apparently, so don't listen to what they have to say
