Pixel Art Image

Using the provided image as reference, convert the subject into a retro low-resolution pixel art portrait in the style of early video games. 
If the original image shows a side angle or three-quarter view, first normalize the face to a straight-on, front-facing orientation with clear symmetry. 
Render the portrait as 2D pixel art with very low resolution, visible square pixels, and strong simplification.
Use a strict monochrome or near-monochrome palette (3–5 grayscale tones only). Apply classic pixel-art shading techniques such as hard contrast and light dithering, with no gradients, no anti-aliasing, and no smooth edges. 
The final image should resemble an old-school game character portrait, flat, pixelated, and intentionally low fidelity.
