My first site done in Xara Web Designer

Hi, well this is my first site done in Xara Web Designer, and some graphics that i imported from Xara Xtreme, can somebody tell me, why the buttons act a little bit weird? Its the same at Firefox and Internet Explorer, i dont know what im doing wrong. Anyways, here is the site link: www.tenpuraben.co.cc . Comments are very very appreciated.

Note: site its not already finished, links redirect to deviantart portfolio, also 2 icons i grabbed from deviantart, when site its finished, proper author credit will be posted.

P.S: Looking for a free web hosting, or free domain withouth ads, if someone has info, pm me please. Greetings from Tijuana, Mexico.
