Looks average at best. Why you'd spend money on that when you have Sascha's world textures which look a million times better is interesting.
Each their own i guess...
Really, the mosaic program is quite different from what Sascha has done. Sascha's is very much like photoreal and generally I don't like photoreal much, not since I spent a bunch on Mega scenery years ago. But what Sascha did looks nice so I'm going to take a look at the screenies of his finished product this weekend.
