well i was observing the picture some more, and to my surprise there are a bit of flaws, some of them cant be helped, and dont neccesarily effect the epicness in the picture... :
1) there are trees arvitrarily sticking out of the rocks, looks sorta funny. Although it doesn't look bad, it jjust cuts off the trees in ways rocks normally wouldn't cut them off ( like there is a tree toward the MAin structure that has its entire base inside one rock, and half it leaves cut off by another rock.
2) you can see the water layers down near the sand. looks strange
3) the path to the main structure looks really out of scale, perhaps making it all a stairwell would be better.
i made these crituques since Void likes better critissm then " this is uber l337 shittzzz " if you know what i mean, so if void ever reads this i hope it helps.
