well, let me start with critique and advice...

1. The colour swatch is all wrong. Mint Green with Grey, big no-no.
2. Make up your mind what fonts you want to use, there's several on that site and bold/normal/italic as well.
3. The Nav bar on the left should be (imo) closer to the main bit. It looks a bit disjointed.

try taking some of the colours out of the banner to use in the site, greens, yellows etc. Get rid of the thick 3d-ish borders everywhere, lose the reflection graphic.
