What's that supposed to mean?
It's using blue on the menu bar entirely out of the blue (heh), it has windows fonts that don't fit entirely, the active window has a border on the window chrome that doesn't exist in the original, along with buttons that touch that and just look terrible, the "about this mac" dialog has non-rounded edges, as well as a greyed-out button that is near unreadable because the text is the same color, and the window control buttons are far too spaced out/small.
