not having it as one mesh is better. We generally split the models up where we wont see the joins. that way we can assign different maps to them (thus we can have larger texture maps on them and paint more detail in) so i wouldn't worry about that.
The only part that looks a little off to me is the nose cone. It looks a little too large.
