There are still a lot of banding and hugging going on, same places as before. Read carefully about it and you will understand it better.
There are also some AA that would be better of not there, on the small green plants for example. The AA around it makes it look flat and weird. Try to not overdo
on the AA when you have such small sprites, it makes it weird to the eye, more blurry then clear. I would also suggest toning down the colour of the bright grass, right
now it's a bit too stingy.
Compare the plant to the flower, the flower looks a lot better because it doesn't have tons of AA around it.
Another thing with the plant. I see you have just rotated one of the halves at put it on top or bottom. This destroys the perspective a bit and I would suggest
you do the top part of it different. It wouldn't take you much time and it changes a lot. Same goes for thee tree, If you do want to mirror it try to avoid things in the
middle that actually makes it look mirriored. Like the two dots on the top middle branches.
I personally would not have an outline for the stones on the bottom since it doesn't melt in with the grass enough, and now with that vague shadow it looks a bit like it's floating in midair.
