I've seen these pictures on eBay before... were you the one who posted the ebay listing on the forum, perhaps?
Well, that doesn't matter so much. On to the review!
Speaking of that picture, it doesn't quite line up with the site. Maybe center it, or resize it to fit the edges of the page. I'd recommend the prior, personally, to avoid distorting the image.
I'm not too fond of the big grey bar that extends past the buttons, I have to say. Perhaps a color that better matches the dark blue would be more suitable. Or just simply use the same blue. The bright yellow text doesn't do well with the blue, either.
Continuing on with mismatching colors, the "Banner Network" text at the bottom of the page isn't readable- it's black, and it kind've makes the banner and the bottom of the page feel off center since at first glance it just looks like the blue link text is shifted slightly to the side for no reason.
I do think it's interesting that you let people post their LED mods, though. Good idea, though it might mislead customers into thinking that all of those pictures were made possible by the particular products you're selling.
