"Create an image featuring a gray T-shirt texture as the background. On it, draw a taller and skinnier stick figure stepping onto a stair, embodying a unique mix of emotions. The stick figure should have a bittersweet smile, combining elements of sadness and happiness, and wear simple, child-like, poorly drawn clothes - a shirt and pants with mismatched proportions and uneven lines. The entire drawing should capture an amateur, child-like artistry, reminiscent of a naive and joyful expression. Aim for a playful yet poignant vibe, as if a child has drawn their interpretation of complex emotions."
