Ooh, nice! Always interesting to see quirky builds
That purple glow of Meridia's orb is gorgeous, and I think you're off to an exciting start with the illuminated plants, corals, and crystals! Are you planning on continuing the project? Did you make the upper balconies overgrown too, or did you wall off the stairs? Perhaps you could incorporate some lights and odd bits and pieces into the little wall alcoves as well?
It has a very cool 'magical city lost under the sea' Atlantis-esque vibe to it! Could be totally exciting to go with that theme throughout the whole villa, with hidden treasures and broken pillars maybe, with some boats shipwrecked (the Argonian ones for example are discounted in the CS currently along with all other vehicles). Anyhow, really inspiring stuff, great job!
