Certainly,
1.Not that white is a bad background, but there's an awful lot of that. Makes the site look "open" and the content look small. So I would try to put more color contrast to bring the focus of the visitor to the content. One can usually accomplish this by making a background color that is significantly darker or significantly brighter than the area in which the context is held. Not to be limited by this though, you can also use graphics with different variations of your color scheme to "close" the site.
2. The general appearance of the site leaves me having a feeling of floating on the site. I would suggest more defining lines to give it a structured appearance and feeling. Give me a defined left and/or right side. Your previous design did this better, but not great.
3. My personal opinion is the tabs on the top either need to go or need to be defined more. The graphics are flat and pastel.
