It's a nice style, but I'm not sure it's a wise choice given that the background image is over 1.3MB in size. Something which will have a quicker load might be a good idea for someone's first look at the site.
A style that causes the site to take longer to load, or a style that isn't accessible or automatically easy to use could end up in loss of registrations. Given PC's recent activity drought (compared to the norm), it would be wise actually taking some time to choose a clean, inviting, and quick-to-load style that is consistent in design/functionality to the broad spectrum of styles that already exist.
