hey thats cool for a first site.
As its been done in flash, it'd be wikid to add some little animations and movement to it. Take advantage of flash! Even simple stuff, just play around!
As it's your own personal site you can try whatever you want, or make a page called 'playground' or something similar. This page could be links to various different 'things' you've created in flash or html or whatever. Create loadsa cool pointless stuff. When anyone asks 'what for?' you can say, trial and error, and experimenting!
