What would improve the terrain in Minecraft

1. Better Mountains: It would be really cool if Minecraft had mountains that actually looked like mountains and not just big dirt hills! The mountains should have their own biome and would be in mountain ranges. They should have bigger and thicker size, more stone on the surface, lots of trees and small ponds/lakes. There should also be another special type of mountain wich should be like a big sharp stone top like the picture of the blog with snow on the top. These kind of mountains wouldn't have lakes or trees, and would be more often spawned near snow biomes.

2. Bushes in other biomes: Bushes should be scattered around like trees, and not only in jungle biomes. You can get sticks if you break the leaves. It should have its own leafblock.

3. Water height: Naturally spawned water should rise and lower randomly depending on the weather and biomes. Rain Weather: A few pixels higher.
Desert Biomes: Only a few pixels high.
Other Biomes: Normal height. (If not rain).

4. Fog as weather: Fog should be a type of weather in Minecraft. It'll look like if you put your render distance as SHORT. It'll be foggy especially in swamp biomes and will occour more often around big mountains than it would other places. When the fog is coming, it'll be like you put your render distance to far all the way down to short/tiny slowly after time.

This is what i think would be a good improvement for the game. It'll create more realism and more varied weather and biomes. Thankyou for reading! I hope you think this will be a good improvement to the game, too!
