50min session on facial expressions

Hi, I'm looking on feedback on these drawings (they're all based on a 2min timer). Trying to improve the faces and style overall. Thanks in advance for your answers ^^

hello, I think you have done a great job mainly with a short timed session. A bit messy (brouillon) with the last faces down but it's ok <3

These are amazing! A bit messy, but it was 2 minutes, I get it. They look lovely!

these are really great and i love them, especially how you draw noses!! you draw different features and faces very well! nobody looks like the same person,, i can tell they are all different people. however, something i notice is the drawing of the head. (nothing bad i promise!!) i'm specifically looking at the second gesture on the left and the one next to it. you drew his head guideline as a circle, but really from the side--and any angle that kinda has the side-- the head is more oval shaped. using a circle makes the back of his head look flat! it's something to keep in mind! i struggle with it sometimes too because im used to just drawing a circle, but drawing an oval for the front/back of the head works very well. for more practice, i recommend studying the skull for basic shapes to apply to future gestures and drawings! <333
