They do look a bit bright, but it might be scaleable in terms of brightness. Scaling it down from that brightness in daytime, and with that night-time shot, would make night much darker. Probably best to tone down the brightness a bit for daytime.
Also, another thing...to be blunt, that host sucks balls. Great big sweaty donkey cojones. I can guarantee that I and a majority of the rest of the viewers will not go to some site on a shitty host that has a homepage prompt every goddamn time I visit the site, regardless of how good the site in question is. Not only is a homepage set prompt discourteous as hell, but it's also irrelevent, and annoying as hell. Why the hell am I going to change my homepage to some shitty no-name search engine?
On that note, I changed the BBCode in the initial post so that it does point to the site, but there's a problem. Something about that host doesn't like it directed to from a message board or in a pop-up window, I guess. From the front page of this site, fine. Copy/paste into a fresh browser window, fine. Clicked on so it goes into a new window, it takes a shit.
