I've created artifacts/image.png: a 512 × 512 PNG of a bubblegum-pink alien in a cobalt hoodie. It's drawn on a 32 × 32 grid and each grid pixel is scaled up to a 16 × 16 block, so the edges are hard and square.

• Character: a wide dome head with two short antennae tipped in phosphor green, two 2 × 2 black dot eyes, a small mouth and one lilac blush pixel on each cheek. No headgear. The hood is down and gathered around the neck, with bone drawstrings and navy shading for the pocket and creases. The bust is front-facing and centred, and the shoulders run off the bottom edge.
• Checks I ran: ffprobe confirms 512 × 512 PNG. A colour scan of the file finds only nine colours: black outline, the #0c1610 background, and seven palette colours (moss, phosphor, navy, cobalt, lilac, bubblegum, bone). That means there's no anti-aliasing and no gradients. Every shape has a thick black outline, and the background has five small green specks. There's no text, frame or watermark.
• Not met or not checked:
  • Nothing from the size or palette rules is unmet.
  • I couldn't check whether it matches the rest of the 787-piece set, because none of the other pieces were provided. Someone should look at it alongside the set.
  • The bottom row of the hoodie has no outline because it runs off the image edge, which the brief asks for.

I didn't use the installed image generator. Generated "pixel art" usually comes out off-grid, with blurred edges and colours outside the palette. Instead I wrote tools/draw_iu_0292.py, which draws the image pixel by pixel using only the standard library. It rebuilds the same image with python3 tools/draw_iu_0292.py artifacts/image.png.

The output, the script and a short artifacts/README.md are all untracked, as required. I haven't committed anything.
