That's the end of the topic, back to tips, what would you say is a good tip for creating a ship
Less is more. Don't go into the fanboyish stuff of "it has 70 phaser banks and 500 torpedo tubes and a dozen warp nacelles". They did that even in Star Trek Nemesis, it was cringe worthy.
Take a look at the TMP Enterprise and the TNG Enterprise. Those are thorough designs, for both interior and exterior.
I'd also look at contemporary ship designs, like aircraft carriers, to get some idea on why things are designed this or that way in the real world.
