A smartphone review thumbnail with a phone in hand, green check, red X and shocked host against a tech grid

Prompt

A thumbnail for a review of the latest smartphone. The phone is held in a hand, angled to show its sleek screen and camera array. On one side of the phone, a big green checkmark icon; on the other, a big red X icon. The YouTuber’s face is in the corner, with a shocked and surprised expression. The background is a clean, techy grid pattern. This demonstrates precise product rendering and the ability to create a clear “vs.” narrative. –ar 16:9
