An energetic youthful character with explosive gravity-defying hair in vibrant shonen manga aesthetic

An energetic youthful character with explosive gravity-defying hair executed in vibrant shonen manga aesthetic with pop art sensibilities. Graphic flatness with thick black contours and limited modeling reminiscent of 1990s anime cel animation. Aggressively bold palette: acid yellow background, teal-green hair highlights, warm ochre and umber skin tones with deep forest shadows. Tightly cropped dynamically angled composition with upward gaze and raised fist creating diagonal energy. Deliberately non-naturalistic lighting using color blocks to define form. Mood radiates defiant optimism, scrappy determination, and youthful bravado. A free phone wallpaper for your lock screen or home screen.
