WWII Spitfire WIP

I started this plane a few years ago and I'm now working on it again to improve on it.  It had terrible geometry and the mesh was just bad (over 4k poly).  I re-topoed it to its current look.  Using Maya 2010 and Topogun.  Am working on getting textures on it.  I will upload those when they are done (soon).  Any comments or concerns?  I welcome all critique.  Click on Image to enlarge
