Seven prompt mistakes that quietly ruin your results
None of these cause an error message. They just make every answer a little worse. Here is how to spot each one and what to write instead.
Describe a character and get a 16 by 16 pixel sprite as crisp SVG, with a small palette and a second frame for an idle animation.
Draw me a pixel art character as SVG. Character: [DESCRIBE IT, e.g. "a cheerful frog wearing a tiny crown"] Style: [e.g. 8-bit console, cosy farming game, dark dungeon crawler] How to build it: - A 16 by 16 grid. Every pixel is one `<rect>` of width 1 and height 1, inside an `<svg>` with viewBox 0 0 16 16 and shape-rendering set to crispEdges. - Six colours at most. List the palette with hex codes. - The silhouette has to read. I should recognise it as a solid black shape. - One pixel of darker outline on the lower right, as if the light comes from the upper left. - Then a second frame for a two frame idle animation. Change as few pixels as you can, and tell me which ones.

A frog with a crown, drawn on a 16 by 16 grid with a six colour palette. In the second frame the eyes close and the body drops by one pixel, which is enough to make the sprite feel alive when the two frames alternate.

Placeholder sprites for a game jam, avatars for a side project, icons with a retro feel, or just for fun. The grid is tiny on purpose. At 16 by 16 you're forced into a readable silhouette, which is the hard part of pixel art anyway.
Describe one clear feature: "a frog with a crown", "a robot with one big eye". Give a character three accessories and at this size it turns into noise. A style reference, like 8-bit console or cosy farming game, steers the palette. If you want more detail, change the grid to 24 by 24 or 32 by 32 and raise the colour limit to eight.
Don't judge the sprite zoomed in. Shrink it to 32 pixels wide, and if you can't tell what it is, ask for a simpler silhouette. When you scale it up, keep the crispEdges setting and use image-rendering: pixelated in your CSS, or the browser will blur the pixels.
