JillValentine standing inside the open doorway of a moving train, one hand gripping the overhead rail while she looks back with a determined expression. Blue strapless top, dark skirt, olive harness, white sweater tied around waist. Low-angle wide composition, wind lifting her short hair, a luminous coastal city beyond the doorway. High-end hand-drawn anime key visual, expressive linework, cel-shaded forms, painted backgrounds, vibrant sunset colors.
