Create a captivating 2D illustration of an anime girl deep in thought, her hand resting gently on her chin. The character should emanate an air of contemplation and curiosity. Dressed in a stylish ensemble, the girl wears a black top and skirt with intricate details that add depth to the 2D aesthetics. Her expression should convey a sense of introspection, with her eyes slightly narrowed as she ponders something intriguing. The hand-on-chin gesture should be executed with subtlety, showcasing the character's engagement in her thoughts. Her posture should be relaxed, suggesting that she is in a comfortable environment where she can ponder freely.
