So fast... Nano Banana 2 Lite generated this image in just a few seconds. Prompt ⤵️ White background, stark, neutral ambient light, no horizon line, pure negative space surrounding the artwork. A single central ink scribble portrait of a man with his eyes closed, laughing deeply with an open mouth showing teeth. Medium/Style: Scribble art, gesture drawing made entirely of chaotic, tangled, overlapping fine black ink lines, ballpoint pen aesthetic.

Loose, sweeping loops and stray tendrils fade out into the white space at the edges of the hair and neck. Subject details: Man in a moment of intense laughter, eyes tightly shut with crinkle lines, wide open mouth exposing upper teeth, defined chin and jawline built from layered pen strokes. Composition: Head and neck centered on a square canvas. Imperfections: Raw, unfinished edges, overlapping chaotic ink loops, erratic stray lines, visible handwritten cursive signature "Linweil." in the bottom right corner. Scribble art illustration, fine-art ink drawing, sketchbook page, contemporary portrait print. Do not use smooth gradients, clean vector lines, digital airbrushing, color, photographic skin textures, or background elements. Do not duplicate or alter the signature placement.
