the back looks good - the front looks too much like a vacuum cleaner. - its just too simple. - in terms of model design .... ( yes, i know its gimp and not an actual model )
its good to take a page from existing models - but its not too good to make it look like a kitbash.
think of what the separate parts of the models are meant to be. - don t add wings when they don t serve a purpose ( applies mostly to factions that don t care for aesthetics - and nomad ships don t appear to be build for looks )
also - think really really hard. - do you really want a F-gun?
nomad ships are meant to be balanced equally to public ships - no more OP gear "cause they face bad odds" - a cruiser with f-gun will be like the lib siege cruiser ( significantly less point defense turrets )
then think of what ships you are most likely to meet ( order / bhg )
and only then - decide if it makes sense.... .
an anti-cap F-gun makes sense vs. ships like the rheinland battleship behemoth. - a ship that actually CAN be hit from afar.
but you will face osiris and makos BBs - which are considerably smaller and more agile. - so .... does a F-gun really make sense for you?
