It is not a bad looking forum
I am not a big fan of vBadvanced as I think that sometimes when a guest opens your site they are not aware that you have a forum and if that is the whole basis of you site then you might just loose some potential members as the first few seconds when someone opens your site decides whether they will stay or not.

With your Header, I like the image that you have chosen as it suits your site but I think that the poor photoshoping of it ruins it a bit.
Why not just use the original image and add your site name as text or you could place just your logo like you have it there, but spend a bit more time making it a bit better

These are only small things but I think they make a difference.

On you board I think that you should reduce some of your forums into subforums until you get some more content. It will look better and you wont have any forums without out posts showing on the home page.

Good luck
