masterpiece, very aesthetic, best quality, score_9, score_8, score_7, highres, newest, retro anime illustration of two samurai figures on a winding forest creek at deep blue night with the composition deliberately unbalanced, the female ninja standing on the left bank pushed close to the left edge of the frame her body angled inward and slightly away from the viewer with her staff held at a trailing diagonal, the crouching cloaked figure on the right bank positioned much smaller and farther back in the frame sitting deeper in shadow so the visual weight sits heavily on the left, the creek itself curving off-center and disappearing behind the right figure rather than splitting the frame evenly, the firefly orbs clustered densely in the upper right and mid-left leaving the lower right corner nearly dark, the forest canopy heavier and closer on the left side pressing in while the right side opens slightly into hazy mountain distance, one large foreground grass stem cutting across the lower left corner into the frame uninvited, 1990s Japanese anime aesthetic, Yoshiaki Kawajiri Ninja Scroll background art style, richly painted cel background with flat character rendering, deep blue and teal nocturnal palette punctuated by glowing chartreuse firefly light, analog cel texture with film grain, vintage feudal wilderness OVA illustration quality
