currently has only 4 skins and we're yet to sync those with the skins of the RadControls for ASP.NET AJAX suite. This is in our plans and hopefully we would be able to do this by the end of the year. For the time being, if this is a show stopper for you, create a custom skin to match the design of your app. For more information check the Applying custom skin to the web report viewer
