Wow, that‘s really really cool. I love the minifigs, they have a nice classic vibe to them. The ships have a great size for playability around the port. Overall you’re really nailing the theme you created. Personally I’d switch the green grass parts for tan sand to give it more of a beachy vibe, but that’s just me. When I was a kid I would’ve definitely preferred this faction over the armada.
Are you planning to extend the theme?
