I like it clean and simple. May be you can put some more effort on the header banner. It's kind of bland.
nice colors, cool use of the left column, the only thing I can see negatively is the bad logo. also you might want to try to change the color of the texts on hover instead of an underline that would make it look better IMO.
At categories on the left the blue shape is a little goofy but otherwise it is clean and simple, easy to to follow
because I heve more focus in contents so I not focus at layout... how about the contents it is OK....???
Not much efficient. Dont think that im discouraging you. Because the web is developed lot, not web 2.0 layouts are so popular. Also it is developed further and moved to web 3.0. Search in google about web 2.0 designs and have some look. You will get more idea.
