You only mentioned some of the aesthetics here Robin, all pages are not created equally code wise either, beauty is not just skin deep, design also comes into play with the coding aspect of any site.
Also there is a time and a place to use images over text or ajax vs static content for indexing/
seo purposes.
I take it your following this up with a view on designing well with code too and perhaps more indepth into the aesthetics such as grids, typography, understanding colour theming (why you should use certain colours etc..)?
