Side-by-Side Results
Prompt
"A Southeast Asian non-binary professional in their mid-30s sits at a clean office desk in a tailored blazer over a crisp collared shirt, hair in a neat ponytail, giving an approachable confident smile while lightly resting one hand on an open textbook. The desk is realistically cluttered with color-tabbed textbooks, a lined notebook filled with tidy notes, two uncapped highlighters (yellow and pastel green), a capped gel pen, and a slim laptop pushed slightly aside; portrait-mode framing with creamy bokeh blurring a neutral modern office background, soft natural window light, polished LinkedIn executive-portrait vibe. Create two render variants comparing Flux Ultra 1.1 vs Nano Banana 2: Flux Ultra looks slightly warmer with richer contrast and crisp micro-detail on fabric and paper texture; Nano Banana looks a touch cooler with smoother skin tones and gentler contrast, both remaining realistic and professional."
