Critique and help please!

Hello…

im working on a small and quite simple site for a friend of mine and would like some suggestions from people who knows this stuff (i’ve only done a few sites before and im self-taught…). Mainly what bothers me is that the site seems to eat up alot of memory… tweens etc seems to be sluggy and slow… what can i do about it? any other suggestions (layout, functionality etc)

here it is… (btw, its not done so, pictures, texts etc. is just temporary)…
