it needs a whole new concept for the nomad ships if you wanne get rid of the "sex toy" look. - nomad ships ARE cylindrical ... and usually slightly larger in the front than in the rear. - so they either look like space mushrooms or cheap sex toys made of an ugly "glow in the dark" plastic.
they re all not very complex - and the sunbuster cannon even looks like a shincter. - i mean.... these things ARE fallic. - trying not to make them look like they do is like trying to make a penis not look like a penis.
