If I were you I would probably change the forum to a different theme other then the default. Make it more you. I would also consider makeing the picture stand out some with a few brushes/textures words etc. Also try making it a bit bigger. It would help cath the eye of alot of people
I think you should remove the top image and change it to something else. Please it is kind of adultish or so and I am sure there are some underage members there.
Well thats not a site from what I can see, its a forum.. it has stock skin and pretty much is a another forum, nothing special about it really, only the picture on the top left :P
