First thing i see is that nothing is lined up and the padding is allover the place. You have to line up your content for example if you look at your titles or h tags the content has to line up with it either from the left or the right, also try to keep your spacing consistent if you use lets say 10 pixels then you have to use 10 pixels throughout the whole template so it looks consistent.
I am not crazy about the menu i think there is too much with the arrows on the top and the bottom also the line on the bottom should line up with the bottom line.
The main page slider nav on the right overlaps the image you should fix this. I would use the PT Sans Narrow font it just looks nicer.
The slider thumbs should hover above the button not on the side. For me the colors make the theme look out dated try to come up with a better color scheme.
the color scheme does not convince me , nav & subnav can be improved .. is a strange feeling to see the design looks a little old .
