I love how square you make Bogart's head. I never noticed that about him. In fact, it's probably not even true, even in his youth he was more jowly and dissipated than this. But you make him more handsome than Jack Warner's wet dream of a movie star.
You can keep your big noses and buck teeth on rollerskates, these are always my favorite caricatures, the ones that make the subject look better than they are.
Very nice portraits of three gentlemen who contributed so much to cinematic culture and to Warner Brothers' early reputation as a maker of popular and "indecent" entertainment (largely for levels of violence we'd scarcely raise an eyebrow at forty years later...).
(And what would Bugs Bunny have been without them...?)
