Firstly, congrats on wonderful color scheme, really grabbed my attention.
1 bad thing: I'm on 2Mb/s DSL, and your banner took a while to download, this isnt the way you embed pictures in web pages ( no Offence my friend), make slices of them, (say 6-8 slices) and convert this banner space in table cells, and then insert one slice in each cell (making sure your table attributes are as follows: table border = 0, cell padding and cell spacing both = 0)
change color of your address. (white/light blue)
other suggestion is post information from yourside, which software are you using? as when i opened the site on mozilla, it dispersed the search button.
other suggestion is: keep consistency in font (use either helvetica, verdana, times), dont make use of too many fonts in your site. (u dont have knowledge of users machines) as Times can be found in windows and mac both, helvetica in MAC, verdana in both, times new roman in windows only. plesae as well refer to some O/S reference of default fonts and colors. btw, are you designing on MAC?
