Is this a russian Tupolev Bear?
Or perhaps the "Peacemaker" bomber?
I think you have a good result right now. You also have the option of refining the shape of the objects. It doesn't have to be all that much work, so if you know how it is "supposed to look like you get results fast. I can recommend the surface-fillet tool, to make those neat middle surfaces, connecting the wing to the fuselage.
It's really easy. If I remember this right, you can use the freeform fillet, by selecting the whole two objects and do use the fillet tool.
You may have to adjust the settings afterwards.
As for the propellers, you can use the "deform-nonlinear deform-twist" to twist the propellarblades you have right now. Delete history and then you have some nice propellar blades.
Looking forward to see more of this bomber!
