Lovely, although I really wish you'd spent a bit more time looking through the new doodads that's come around since last you were around. There are some really good ones that could have enhanced the overal graphical quality of this terrain.
That said, I love the idea, and I really like the eclipsed sun, the mystical tree of life thing going on and the floating boats. Very neat. The colour pallet is top notch, stark and vibrant, weird and mystical.
The only part of it I'm not a huge fan of is the waterfall in the middle, it seems odd that its halfway hidden behind the other floating island, and it ends rather abruptly. You can actually make a cool looking water to mist kind of transition by using the eerie fog doodad and flipping it around, then putting it in front of where the waterfall ends.
Anyway, this is a very nice comeback Oziris ^^
