Hmm, depends on how you see it. They aren't bad considering the basis you worked with ( the tile Unknown made ).
The reason why I made it an example is that, well, beaches/sand don't usually.. take on a platform-ish shape like that. The tiles are usable to form just about anything, but they look unnatural.
That's more or less the point of my preference for "style", or whatever better formulation you might have. ( The last two thirds of this post were directed at everyone, by the way. ;o )
