I'm totally digging the bubbles in the header!
However, the 'click to activate' nonsense interferes with the control panel; isn't there a simple fix so IE doesn't do the box around the flash? The exact fix escapes me, but I've done it on an asp.net site I built once, so could have a look if Google is of no help...
And as mentioned above, the menu needs to be moved down a bit, or the logo area truncated...perhaps make the 'Artesian Spa..' text in the logo a few pixs smaller and right/center align on the logo graphic itsef? Same with the chick in the tub...a bit too big, given your current logo size settings.
