Not going to lie, I'm already missing the old UI quite a bit. It was simple and easy to read. If you're going to change the colors of something that's supposed to have text on top you need to use contrasting colors, so that the numbers "pop" and are easily read. That was the whole reason you added black text to the post encounter/results text box isn't it.? The white text on white/green health bar is tough to read (same goes for the Mana bar). Granted health text gets easier to read the lower you go but health should be readable at all times.
I also prefered the old Stability bar rather than white text on a mostly white image where the text also covers the image that's supposed to represent your balance. Is there actually 9 Status effects you can have active in a fight? Cause if not it'd be nice to see one of those bubbles gone and replaced by a Stability bar. As well as possibly increasing the size of the text/bars so again they can be more legible and not compressed so much, they're practically half the size they used to be.
Another recommendation for the end of an encounter is to have an arrow, checkmark or something to point to the way the battle was ended. From what I could tell it was just the image slightly highlighted compared to the others.
