Introduce more content rather images
Avoid flash to improve the site loading
Add appropriate tags to images
Create well defined directory structure for the website

Your site looks fresh and modern, while maintaining the same brand image you're offline. Choose the same colors for your website if you use in other marketing materials, and the same logo. The site must be visually appealing, with many interesting features, but not too fussy or distracting. The layout should be easy to understand, let visitors to the site easy to navigate to the pages they want.
