That is a excellent skin
The logo is perfect, simple and well tailored to the site. The gradient really works well in this area. Your choice of an image also fits well and gives the site a logo that stands out. Great job.
Some of the images are very light and almost impossible for me to see. (noavatar.gif and forum_old.gif). This may be by design as the forum_new is probably darker to draw the visitors eye.
The Welcome message is stock and could use a bit of customisation, if only to drop a keyword or two there.
The buttons are a bright blue and do not seem to fit with the colors in the rest of the style (newthread.gif). Having these match the gradient in the title bars would make them match and look better.
In the gallery I am getting a missing image to the top left of the login area (

In all you did a fantastic job with the design. It is very easy on the eyes and just looks great.
