You could use pixel fonts or maybe use dynamic text fields in flash rather than the static ones you appear to be using at the moment to sharpen up the smaller text (just remember to specify ones everyone has, or embed them)... if that's why Oli's suggesting pixel fonts? but then again he does seem to have a particular love for them judging by his own sites
Like the side swipe motion bringing the different pages on screen.
Maybe you could load the pictures into the main site rather than having pop ups? easy if your using MX a bit more problematic if your using 5 or earlier !? just ad to the overall dynamic of the site.
