Your latest trees are very pretty. However I have a few suggestions:
On the first tree, the base of the trunk is much too wide. Looking at how the two branches come down to the trunk, the trunk should be much narrower. Half as wide at least.
The second level of branches after the first two main branches off the trunk also seem abnormally thick. I might make the radius of those 1/3 less.
And lastly, the leaves on that second tree are afully huge near the bottom. It's clear you're changing the size of those quads from the top to the bottom of the tree. But trees aren't built like that. The leaves over the whole tree are the same size in general. Maybe they are a LITTLE smaller near the top where they're younger, but nothing like the difference you have there.
