I've just given this site a redesign but I feel like this needs something else, any ideas anyone? http://www.sebsanders.co.uk/ Thanks
rounded corners and a bit more whitespace between the boxes and remove the black dots from <li> in your left menu !!!
I fell there is too much white space at the bottom of the page also can u make the buttons look 3d? or make them stand out more. The rest of the site looks good.
Make a footer. Add some links to important categories of your site, contact etc and/or use it to exchange links with related sites.
Left menu. I think you should more clear font colors. Hmm, then if you can, make your corners rounded. That's all. That site is looking really good.
