Good work,looking good.Couple of suggestions if you don't mind,try setting your material for the propellers to blur instead of normal in the material editor(click the little downward pointing arrow near middle top of the page in the editor page) and there is quite a bit of banding on the main fuselage (dont know if its intentional but if not) you need to smooth your mesh by selecting the mesh and clicking the small E symbol to edit the mesh and select smooth.
