A young female scientist in a lab coat holds a glowing beaker in a watercolor classroom with a blackboard and planet posters.

Horizontal children’s picture book illustration, soft watercolor and painted texture, clearly hand-drawn and storybook-like, simple but high-quality. A young female scientist who looks warm and intelligent, slick-back hair into a curly bun, recognizable facial features, gentle expression. She is wearing a white lab coat over a black hoodie. She is standing in a classroom-style science lab (not a high-tech lab), with desks, books, and posters. On a desk in the corner there is a small pyramid model. She is holding a glowing beaker with a soft golden light in her hands, symbolizing curiosity and discovery. The art style is soft, painterly, and easy to draw, with visible brush strokes, muted pastel colors, cozy and whimsical. The illustration fades out gently into a white background around the edges, especially toward the bottom and sides, so it looks like it fills an entire picture-book page with no hard border. Calm, warm, magical atmosphere. No harsh lines, no realism, no 3D, no anime, no sharp digital shading. See more
