Soviet hand-drawn 2D animation still from the late 1970s, painterly gouache and watercolor backgrounds on textured paper, soft edges, almost no black outlines, muted palette of ochre, umber, grey-blue and warm white, gentle film grain, flat lighting with soft atmospheric haze, characters drawn simply with expressive silhouettes, no 3D rendering, no glossy surfaces. A 19th-century naval classroom with sea charts on the walls. An older naval officer with grey sideburns in a dark uniform holds a divider over a chart and looks at a cadet with a slight nod. The cadet is the boy from the reference image, now in a dark naval cadet uniform. Close-up on the officer over the boy's shoulder, warm daylight from a tall window, vertical 9:16, no text.
