First thing that struck me was that the colour scheme of the logo doesnt match that of the rest of the site, this gives the impression of a template being used with a logo you had to make yourself.
Other than that the layout I think is pretty nice,
I have experience with this script. It's a real pain in the you-know-what to customize. Right now I think it looks incomplete. I think it would be worth it to customize the whole thing rather than just a few images. I realize that means changing about 20 images alone on the first page but in the end it will look better.
