this was your latest work and you were having a bit of fun with us. Looks good, but not quite a standalone design... very derivative except for the front. The taper at the rear of the cabin make the quarter view look strangely proportioned. If it stayed near body width, it wouldn't look so odd from that angle.
BTW, you should check out the T-splines add in for Rhino... I think you could really progress in that environment.
