is this skin made by you???
i see that you made it your self , let me tell you what it needs.
the header is very dull , try increasing the opacity of the header

and the top bg of the forum name title is also not working
i dont know if you are familiar or not i used to make ipb 1.3 skins and i got inspiration/tutorials/help from
www.ifsz.com thats a great community with loads of skins and also their site has a skin maker
Have a nice day
