A detailed sketch of a futuristic sci-fi spacecraft, featuring enormous warp engines surrounded by intricate formulas and annotations, with each part meticulously schematized. The design subtly incorporates the golden ratio, adding a sense of harmony and balance. With intentionally crafted fake details, the artwork exudes a complexity that invites closer inspection. The rendering is evocative of a trending Pixiv Fanbox aesthetic, employing an acrylic palette knife technique that adds texture and vibrancy. The style is an imaginative fusion inspired by Makoto Shinkai, Studio Ghibli, Genshin Impact, James Gilleard, Greg Rutkowski, and Chiho Aoshima, creating an enchanting visual experience that balances whimsy and wonder, blending the dream-like narrative of anime with the intricate detail of contemporary digital art.
