Immense progress so far, how inspiring

I don't really like the tree on the left in the new version. I don't know, trees don't change color that way do they?
The foliage is really well done, I'll be sure to use those trees for reference to understand how you pulled it off. Just one thing however, I'm surprised not more people commented about this: the trunk looks strange. It's like the foliage and the trunk don't have the same style. The foliage is pretty normal but the trunk is all bent and twisted Tim Burton style and I don't think it goes well together. I hope you'll give the trunk another go so that it fits the style of the foliage better.
As for the rest, it's awesome. It's great to see you persevere and improve at such a fast pace.
