Well, valid XHTML Trans 1.0 and valid CSS, and nice colour scheme (I'm overlooking the fact you use that horrid American spelling of pyjama ) and it seems quite readable. I'd maybe consider jusifying the text running down the central part of the page rather than left aligning it; makes it neater.

I notice that a lot of sites go for the tucked into the left approach but, in my opinion, it's nice to set the margins to auto in the CSS so that the page centres itself if the browser is using a resolution greater than 800x600.

I would also make use of the a tag's title attribute so that when people move their mouse over the links the ToolTipText appears. The web credit link would be better if you used their name; nice to be nice.
