Generally you can do better by just looking up real-life images on google. If you insist on BL examples though, look up BAN and ARES (Blockland Alliance Navy and "Argos Rho Expeditionary Fleet" clans) and look at their builds.
ARES has turned into a more generic "forget around" clan since their initial days as a really good spaceship building clan, so don't let initial searches faze you if you don't find anything good at firts
