This gives a good impression of the world, and I especially love the changes to the rain forest :)

However, I personally feel like the 2nd screenshot for the Taiga looks a little bit off, because while the bushes on the right hand side seem to be ~20cm+ in height, the flowers depicted on the ground texture partially look like up to ~12cm tall themselves. Yet, they have got a height in-game of 0cm.

Maybe there are constraints in place such as playability (distinction between plants to interact with, feel of the area to be more different to biomes with lots of ground coverage etc.) or performance. Perhaps using a texture with plants that aren't visually that tall would make it look more consistent. Or a short and basic 2d composition similar to the bushes as an alternative.

Nice to see the world coming to life :)
