the first one has way too much empty space (note the pun) and in all three the pages are a bit too long
Ok im going to be blunt with you, your websites are really bad, but my first couple looked the same so you are following in hallowed footsteps. 8) you have to many animated gifs, the pages are to long, poor navigation, no search engine optimisation, the colours are all over the place and the content isnt well presented. Get rid of the animated gifs and the tiled background, shorten the pages, put a very obvious menu on the left like simple text links inside tables would be good, learn some on page seo at some later stage then get photoshop and learn some graphics design. To start off learn HTML and how to use tables properly. if you get bogged down and need help just ask me.
