Well, well, well, well, AuntHerbert, I'm really, really amazed on how well you've hatched your face and expression in outlines (contours) Very sculptural in your approach to facial skulls and muscles.
I like the subtle range of expression in this expression, but I'm just not getting enough of the caricature and cartooning of the facial features and head proportions and angles. Would you llke to please loosen up your facial feature gesture drawings with 90 minutes of 15 second expression drawings, plus some practice sketches of some Uderzo sketches on this link here?: https://andreasdeja.blogspot.com/search?q=uderzo (5400 seconds/15 second=360 warm ups of faces, all flipped horizontally and/or vertically, and normal, too.)
The reason why you could and should do this is because, it can and will be able to get you to loosen up your drawings of the faces with the right side of the brain. But wait, there's more; it can and will be able to help you in your character designs for your animations and comics.
Good luck, Herbert, cheers, and I hope you'll find these helpful, and completely and totally useful.
