Space/Robot building tips

I'm trying to design my own space craft with interior, maybe even multiple levels: however, the ship can also turn into a giant robot. The ship is owned by a bounty hunter Anyway I can't find any good tips or building methods on YouTube for making a spaceship with an interior. I really don't want it to end up looking blocky Any advice would be appreciated thanks submitted by /u/Inevitable_Bid_5902 [link] [comments]
