I just tried with Deepseek and got this for the Mona Lisa

           .-""-.
          /      \
         |  _  _  |
         | (o)(o) |
         \   /\   /
          |  --  |
          |  \/  |
          |      |
         /   --   \
        /  /    \  \
       /  /      \  \
      (__/        \__)

It might not have been the most scientific test
