Chunky pixel art on a 32x32 grid scaled up, every pixel a hard square block, no anti-aliasing, no gradients on the character, 1-pixel black outlines, limited retro 16-colour palette. The attached base.png is the base character. Draw 3 legendary one-of-one versions: complete 1024x1024 images with an opaque background, same character and style, each a unique full concept.

Keep EXACTLY the base's framing, pose and placement (facing straight at the viewer, both eyes level and looking at the viewer, head centred left to right; framed head and shoulders: the top of the head near y=210, the neck meeting the shoulders near y=740, both shoulders and the upper chest in the picture and running off the bottom edge; the arms are down and out of view, nothing in front of the chest; extra detail from the creator: looking straight at the viewer, relaxed confident expression), head at the same size and position, so they sit in the grid with every other piece. pixel astronaut, golden pixel statue, glitched rainbow version.
