In my opinion the background just doesn't contrast enough with the foreground. It's basically the same shades as the content area.
The problem with that is that it attracts the eye as much as the content, but it's not nearly as important as the content.
Oh yeah, and the changing pictures all look stretched.
Out of my control as that is how the mod is programmed to operate.
Just my "two cents".
That's a default background as I ran into issues with individuals that use a wide screen monitor, so that's in place until I can find something that works.
Edit - Your username/password fail message is in an unexpected spot. I had to look around for the message that I failed to login. I suggest putting it closer to the login box somehow.
Again, out of my control at this moment as that is programmed into the template.
Edit 2 - Well, you did say "judge me". I was browsing around some more, it bothers me how the contact page, about us page, etc., all have the same slide show and news sections. If I click on a link, I'm interested in reading about what I clicked on. I don't feel like being bombarded with the huge slide show every time I click something, I already saw it on the home page. It's redundant and hogs lots of space.
Matter of opinion. I've had others tell me they like it as it resolves having to back track every time they click on a new area. I'll work on a happy medium, but again, it's all dependent on the person.
