Prompt: An evocative portrayal of a jazz singer onstage, masterfully composed by (Gustav Klimt:1.2) and (Jack Vettriano:1.2), her (sultry:0.8), soulful voice resonating from the canvas as (golden notes:1.2) entwine with her raven curls, the warm glow of the stage lights casting (rich shadows:1.2) on her face, as a dreamy (haze of blues:1.1) and reds envelop the smoky club, capturing the essence of a bygone era.
Negative prompt: A jarring depiction of a failed karaoke performer, crudely sketched by a spiteful amateur, their voice grating and off-key, as discordant (scribbles:1.2) mimic the cacophony that emanates from their strained vocal cords. The cold, (unflattering:1.1) glare of fluorescent lighting casts (sickly:1.1), washed-out tones on their perspiring face, while a background of (drab, lifeless grays:1.3) and mismatched patterns amplifies the sense of unease and cringe-worthy failure that permeates the scene.
