1. In terms of navigation the wave mouse over link and a list drops down is good. Makes navigation fast and you can scroll through to find the most appropriate option without committing to an option.
As for National Gallery Site.

2.
As soon as you enter the site there are clearly marked links organized in to most commonly wanted options.

3.
The vast expanse of space combined with the reduction of initial links and images draws the eye to that which is there. By not having an entire plethora of information thrown at you initially you can easily select the correct link and move to the specific area you desire. The disadvantage to this type of arrangement is whatever you want to find you are going to have to navigate to a specific area before you can reach your final destination. ( as for the Kringas Architects website image above).

4.
Once a navigation link is selected it opens to a page specific to link. Containing specific images and information. I mean this more in terms of navigation.
5.Left aligned links with the text running up the page. (As for cropped image; left)
6.Background colour is carried through under the text. Allows better continuity throughout pallets. See the National Gallery screengrab above.
7.Considering if the site is a liquid site or not. If the site is liquid to a certain point but then scrolls. Do we scroll to left/right eg 920 ppi. Do we scroll up and down. At this point I think I will have the page as a set size and links will navigate you around as opposed to scrolling down.
