I thought the 'ruled out' could be a little more prominent so I could see my progress.

This is totally important. This is why almost all shopping carts these days use 1-2-3 style steps. The technical term (from User eXperience) is scent, and it's what gives the user a continued incentive to keep going.

I almost quit the StyleEngine until I saw that, but I almost didn't see it at all.
