Great job mate !!!! I think that improved the model a great deal !
If i may suggest something again: Try to add a subtle "highlight" to the bottom of the aircraft. Not a highlight like you have on the upper side of the aircraft but just a lighter shadow. That would give the impression of a undercast (or ground) reflecting on the lover side of the aircraft...When done right, it can look very nice..might be worth trying ?
Also, donīt for get the shadow cast by the propblade on the fuselage. I have always had a hard time figuring that one out, so i tried make a simple model in my 3d app. that shows how such a shadow might look like (the sun is coming from a 10 o clock high position)....hope you can use it
