Very cool, it has more shape to it now :-) The color scheme also looks more complete and the new lights are better placed. I would agree you should look into completing the roof though, but perhaps you should stay with the grey plates for that to give it a center stripe there like the ones on the sides :-)
Definately much better! I love the new sides, rear, and front; the details are a great and it doesn't look messy now. I'm not so sure about the top though; the grey plates seem out of place and I wish it was filled in more. But overall, a big improvement!
