I'm having trouble doing faces downward any tips will be appreciated 👍.
Nicest work on your gestures of your expressions, however, the gestures of these faces could use a little bit more expression, for lack of a better word. Would you care to do 1 hour of more 30 second quick sketches of faces and expressions sketches? As a result, you'd be able to draw your facial expressions a lot less heavier and a lot more lightest and free-est in your range of expressions and emotions.
For more details, please look into the face sketches in the Ben Caldwell book, Action! Cartooning. Let's hope these help.
