i like the colours but i don't like the use of satin in the header boxes, just doesn't look right.
if you really want it to look different than other php sites then you need to get away from the banner-across-the-top-3-coloum-layout-design.
seeing as you are using photoshop and the layout is all images you should try to do something that is difficult or not possible with just html.
overall i think the design is nice
