Yeah, that looks almost completely different in Firefox (which is the browser you should code for first as it's standards compliant). And I think the only real issue with the design other than that is the red background color.
i don't usually like red but in this case i think it looks great! its bright vibrant and shows life. i liked that there wasn't too much on the page. its calm. yet alive.
Distorted in ff for me too. I think the background is ok. I dont like the font used in the images though. The text in the lower right doesn't look proper when right aligned. Maybe use justify instead. It also needs to be taller or centered vertically.
