Thanks! It's just an extrapolation of the existing bamboo leaf texture, but I'm really happy with how it turned out.
Have fewer leaves per bamboo
I guess it depends on what pictures you use for reference, but the ones I used looked pretty dense. Like, dense to the point that you can't see the sky outside of the path. (E.g., 1, 2)
Put the leaves higher up
I should have included more pictures, the canopy height actually varies quite a lot. In some places it's as low as 3-4 blocks, but in other it's easily double. On the whole though, I think you're right. The leaves are much lower than their IRL counterparts, and it could be better
Use a different biome name
I could get behind that. Personally I like the "old growth" term. It's a legit term, meaning "a forest that has attained great age without significant disturbance, and thereby exhibits unique ecological features". That said, "leafy bamboo jungle" is definitely more memorable and fits just as well.
Bamboo Leaves, and a Leafy Bamboo Forest ( kbin.social )
Now, yes, bamboo already kind of has leaves, but not full blocks of leaves, which is what this post is about....
