Three small bits of feedback for you Petninja, which you may or may not already be considering.
1. Make a custom boarder to the minimap that is a little larger and goes with the overall theme. Probably should hide the icons as well.
2. You could also add some custom border to wrap around the chat window. Like the minimap, parts of the base UI stand out because they don't go with the overall theme.
3. The text that overlaps the health and mana bars is difficult to read because of how you chose to represent the bars. As an alternative, I'd recommend moving the text off to a side to make it more readable. For example, condense the two bars inwards and then have a little block to the left of the player frame and to the right of the target frame where text is displayed over a more reading friendly background. Not being able to easily read critical information quickly could make the UI less practical. While a pretty UI is nice, a playable UI is more important.
