What it does
A finished poster or piece of art as a PNG or PDF, with a distinct look rather than a template feel. Describe what you want and the skill makes the image itself. It works in two steps. First it writes a short visual philosophy, naming a style movement and describing how it uses space, form, colour and composition. Then it draws the piece on a canvas, with very little text, treating words as an accent. Craft comes first: careful spacing, a strict palette and balanced composition. You can ask for another round to adjust colours or layout. Output lands as a file you can print or share.
