Cool UI man. Nice and clean. Not often I see UIs with the abilities at the top of the screen. :P
Just a few things though...
You say you don't know your bindings well enough and that is why you have your bars at the top... But you can't really see the binding text anyway - it gets cut off D:
What is the white box in the middle, below your portrait? Sticks out like a sore thumb and takes up a fair bit of room :\
And finally, what is stopping you from putting your skada inside the panel beneath it? (Opposite side of the screen to your chatbox) Is there something else which appears there? Also you should remove the icons from skada 'cause it looks crap hehe.
