Just a few observations:
- Validate your HTML, your code is close, but not quite valid.
- load time was extremely slow, try to decrease your file sizes
-the main image (index_r7_c7.gif) would probably be better off saved as a jpeg, it is a little pixelated
-on your products page, you have 3 links (web design/interactive multimedia/graphic design) all of which link to the same page
-i would suggest not creating your contact "form" in a new window, it was blocked by my popup blocker, also, as noted by PoorDoggie, you should really use PHP for contact rather than mailto. if you have questions about how to do this, just post back
-I like the silve/gold/platinum box along the bottom, but I felt like they should link to their respective pages (in your case the products page)
-The Nav Bar (font/effects) are really fuzzy & tough to read as are most of the fonts in the site, I know it's nice to have "cool" looking fonts, but readability should really come first, try to just go with a basic font for the main body text
Overall I like the design--it's clean and seems to be well thought out. Good job!
