TikZ silhouette of human face seen from the side

Based on Mark Wibrow's answer, but I took your image and traced it in Inkscape, then used the coordinates from the SVG file (opening it in a text editor and finding the list of coordinates of the only path in the file).

By the way, in the image you want to recreate, the camera viewfinder seems to be positioned too high (pointing to his eyebrows). I fixed it in my example.

Not quite as detailed as the required picture but created using Inkscape and copying the path from the xml editor into a TikZ path using the svg.path library:

\documentclass[tikz,border=5]{standalone}
\usetikzlibrary{svg.path}
\begin{document}
\tikz\fill svg {M 29,64
