You’re wondering why I suddenly decided to tackle a 1/250 scale model, right?

Well, let’s just say my greed got the better of me—when I saw there was a fish tank aquascape competition coming up, haha!

So I figured I’d whip up a couple of designs and see if I could snag a spot on the leaderboard~

This model is called “Underwater Ruins: Deep Tide Research Institute.”

By the way, here’s what it looks like once it’s placed in the tank:
