Hmm, everything is great, but I'm confused by the button for the gnome's skill wheel; the brown head blends in with the background in the first screenshot. I can imagine my sister saying, "I can't see who that is." I would style the buttons to look more classic, either with a green button and a yellow emblem, or just yellow emblems.
Can you show an example of what you mean by "styled to look classic"? I don't quite understand.
