Hi David
The side profile looks good. I think the top down view shows that there is a subtle curve missing across the front "edge".
You can see better here:

The beauty of Shapeways is that people can buy as and when they can afford things. You could also offer people choices of material (though personally I am not sure that any material other than FUD offers a smooth enough finish, though possibly some of the polished material).
Looks great anyway and I'd love to get my hands on one!
Cheers, Mike
