Hmm. I still think that the cockpit should be mainly inside the fuselage, rather than almost completely on the surface. If you look at the Serapis for reference, it seems like that Vasudans like to put a cockpit in the body and give it a tiny window, rather than stick a guy completely in some tiny "blister" as mentioned before. Even doubling the depth of that cockpit would make it look loads comfier.
As for the normal map suggestion, I just didn't see how some parts of the bomber would look much different depending on usage of polies or mapping (side "wing" surface), but I guess if some people can't use normal maps, that's fine. I guess I was hoping that more polies could be used for more details, but looking at the bomber now, there isn't too much that can be added to it, so freeing up polies is a bit useless.
