Looks pretty good! However, a few things are setting off my OCD-o-meter:
- The castbar... why is it shorter than the spelltimers?!
- Why is the chat frame so large? It is unbalanced by the DPS meter on the other side...
- Have you thought about putting the names of the raid members ON the raid frames? It would save room and clutter.
- Why do the target's debuffs not have the same border as everything else?
- Last thing, you should probably give everything the same amount of padding from the sides of the screen. It will give the UI a more uniform, clean look.
