Turn my photo into a YouTube thumbnail. Cut me out and place me on the right third, from the chest up, big enough that my face fills about 40% of the frame height. Exaggerated but genuine surprised expression — raised brows, wide eyes, open mouth. Add a thick contrasting outline and a soft drop shadow so I separate from the background. Background: a strong two-colour gradient with a subtle radial burst behind my head. Leave the left two-thirds clear for a headline. Punchy saturation, high contrast, everything legible at 210 pixels wide. Keep my face, bone structure, natural skin tone and identity exactly as they are in my photo — change the styling around me, never who I am.
“Use it” opens the editor with this prompt already loaded — add your photo and generate. Copy works anywhere else: ChatGPT, Gemini, Midjourney.
Open the thumbnail at 210px wide before you use it. If the expression stops reading, make the face bigger.
