A realistic photo of someone's hand holding a blue ballpoint pen, actively underlining text on extremely messy, cramped handwritten notes on white paper. The hand is naturally positioned in the frame. Shot from above at natural angle. 3:4 aspect ratio (vertical).

Visual requirements:

- 3:4 aspect ratio (vertical format, ideal for social media)

- Hand with blue ballpoint pen VISIBLE, actively underlining a key point

- VERY dense and cramped - paper almost completely filled with writing

- Handwriting rushed and sloppy BUT still readable - clear structure maintained

- Lines slightly wavy, not straight

- Words varying in size to fit space

- RED PEN marks throughout: circles, underlines, stars, boxes (NOT complex emojis)

- Simple hand-drawn symbols only: arrows (→), stars (*), checkmarks (✓), crosses (✗), exclamation marks (!)

- Some crossed-out corrections showing thinking process

- Varying pen pressure creating darker and lighter strokes

- Small notes squeezed into margins and corners

- Photo from above at natural angle, natural lighting

- White paper (can be notebook page)

Balance: messy and authentic BUT readable and structured. Like real study notes capturing maximum information urgently but systematically.
