it's a very difficult thing to exaggerate a famous face the way people expect when the reference is from such an extreme angle.
i would recommend making some observations and exaggeration choices using other ref, from simple straight on/ three quarters/ profile angles. this way you'll have a better sense of what he looks like.
then, you can apply these exaggerations to your more extreme angle, thus caricaturing the subject and not the particular angle/ref.
