i love the header part. except those tabs at the top left kind of throw it off... try working with that to make it look more symetrical and also your little content/news boxes are unaligned and seemed to be tossed randomly. and the boxes to the right shuld be evened up and all look the same. but other then that i love the color scheme and the banner area! oh and also, i believe ur HOME ABOUT DESIGN and CONTACT texts on the top left tabs arent aligned evenly either. you shuld use the "ruler" in PS to make sure everything is aligned.
The header is awesome nothing to add, but when I scroll down I dislike some ways done. The font used to descripe yourself should be another font, and it seems like you had a hard time putting the info in the box In Photoshop.
