a bit too wide and flat in the ending. it is the only thing i don't like of your ship, both for texture and geometry
the warped areas are those on the side, where you can see those diagonal line distorted.
You probably may be able to fix it with lithunwrap (or probably with a different texture)
the point is..
what is this nose for? an opening hangar for civilian small ships? an element to let the ship dock with some space stations? maybe something else? an hydroponic garden for passengers? a giant swimming pool?

decide it's role and texture/model it consequentially
