This is a nice little MOC. Good job on the spoiler. The one thing I might suggest is to try making vehicles that are slightly bigger. The Lego Company is notorious for making "minifig-scale" models that aren't actually to scale. (e.g. one-seater cars with no extra room) For an example of the discrepancy, see this picture (http://www.brickshelf.com/cgi-bin/gallery.cgi?i=1873634). Also check out my Model A Ford here - http://www.mocpages.com/moc.php/17996. It's almost a bit too big, but it might give you an idea of what I mean. Good job, and I hope my comments help...
