New biomes and new vegetation

It is true that minecraft has different types of vegetation and biomes, however, they tire, for all the time being the same thing.

I think that adding at least 5 or 4 new biomes, with totally new vegetation, it would be cool, for the player to have more desire to explore the world and even new woods of new trees, even if they are not so different from the current ones. A specific type of animal can also be added for each biome, and may even be born in others.

Examples of biomes:

thick

caatinga

steppes
