小さなドット絵アバター

Create a compact pixel-art head-and-shoulders avatar of an original fictional adult {{gender}}, age 29, with {{appearance}} and a {{expression}} expression. Use a deliberately low-resolution 32-by-32-pixel design language, large clear pixel clusters, a {{palette}} palette and a simple dark outline. Front-facing composition, centered head, minimal clothing detail, plain {{background}} background. Keep all important features inside the central 75 percent for circular cropping. No fine photorealistic detail, antialiasing, gradients, text, border or watermark.
