Monochrome manga art style, female figure with vibrant blue hair cascading down

Monochrome manga art style, female figure with vibrant blue hair cascading down her back, seated in fitted dark jeans, positioned from behind, intricate linework detailing hair texture and folds of fabric, subtly dramatic shading emphasizing the curves of the body and the depth of the scene, soft gradient shades transitioning from deep blacks to silvery grays, the background softly blurred to enhance focus on the character, contemplative mood conveyed through the relaxed posture, slight lean suggesting introspection or daydreaming, hints of accessories like a simple wristwatch slightly visible, the composition drawing the viewer's eye towards the elegance of the figure, capturing the essence of classic manga art with dynamic angles and expressive features rendered in rich monochrome tones, delicate balance of shadows accentuating the contours of the body, overall harmony in color palette focusing on shades of black and gray to highlight the striking blue hue of the hair, evoking a serene atmosphere that invites contemplation of her story.
