A nice theme.

However, a few little niggles I have with it (graphically). The logo could be of higher quality, it looks grainy and feels like an image that has exceed it's maximum colour except it isn't because it's png formattted. The text could be clearer, again, it looks grainy and not as prominent that it should be. In a nutshell, it should be standing out from the rest of the page fully of vibrancy imo.

The navbits_start.gif & navbits_finallink_ltr.gif Don't match the style, it lacks consistency with the rest of the images of the WOW theme.

Another extremely annoying grievance is that sortasc.gif icon. It looks like it's got white matting around the edges. Either that or it's been cropped, Did this icon happen to come from another source? (just asking).

A suggestion, With regards to the button set. Instead of settling for the blue coloured font why not opt for a rich golden yellow coloured font? Giving it a more prominent look rather than the dully hidden away blue the rich yellow would break out the darkness.

Overall, a nice style. I would personally spend a little time and tracking back with some of the images and create higher quality, consistent visually looking graphics to complete the graphical side of the theme. Nice work.
