Quick site critique

Link: http://www.abgnet.co.uk

Just a fairly quick dynamic image gallery site. There isn’t any original content at the moment (so only design critique required!), but pretty much everything in it is loaded externally from a single xml file. I wasn’t looking to make something over flashy, but something simple that would let the content take centre stage.The intention is that the gallery could also be used as a standalone portfolio site, with external movies being loaded into the main panel (e.g. when you click the sample “about” or “contact” links) that draw their content/properties from the main xml file.

Critique much appreciated, thanks!
