Well, this is as far as I'm gonna go. I'm really not an artist.
I added a little thing on top to break the surface... not sure what it does exactly. Fuel coupling?

The front window is bigger as requested. In this picture you can see the coupler on the back.
.wings file is attached if anyone would like to continue this model.
(Ignore the artifact on the fuel coupling thing. The tilted black "v". It's just something to do with Wings3D's renderer and I'm too tired to render it again. I've been up for 2 days now, time for bed.
