Why? Even though it might not look like a shopping cart skin, the layout is too squarish. No smoothness shown which makes the viewer see your overall presentation at "ease"
Two points you might want to take note:
1) I think you have used the TM script to show on the front page. I would suggest adding one more column to it because there are so much white space left and you end up with a longer scroll bar.
2) In your contact list, I would suggest you remove the grey bits on your contact info. doesn't look good with squares and rectangles all over the place.
