A drawing black and white of a highly detailed futuristic underwater Japanese-inspired house called “Sakura Abyss”. A large transparent dome shaped like overlapping sakura petals, with organic structural beams designed like cherry tree branches. Soft pink light filters through the seawater, creating delicate reflections. Around the dome, an underwater zen garden with nacreous white sand arranged in karesansui patterns, coral rocks placed like traditional zen stones, and small colorful fish swimming gracefully through the patterns. Inside the dome, a minimalist ryokan-style interior with modern tatami-like flooring, sliding digital shoji doors displaying animated sakura blossoms and flowing water. Warm soft lantern-style lighting. In the center, a holographic cherry tree with glowing petals slowly falling in the air. A bedroom with a fully transparent ceiling where koi fish swim above, creating a peaceful inverted pond effect. Highly atmospheric, calm, ethereal blue tones, soft shadows, ultra-realistic and anime-fusion art style, extremely detailed, high resolution, magical and serene. See more
