I took a look at your work, very good, though I would prefer the style of picture 1, its still excellent. A few concerns; firstly, the village generation needs to be worked on, the village tries to replicate the shape of the dune, it would be better if the villages were their own custom biome that was flat and separate from the rest of the regular dune biome, secondly there are far too many cacti, about one every nine chunks is more realistic in the world of dune. One more biome (besides the suggested dune, village, and polar ones) needs implementing, the rock outcroppings, they shouldn't very common, but shouldn't be as small as the islands in ocean biomes. Thanks for listening (or rather watching) me ramble.
