Hello there, leofelco816,
That's a very excellent face you've quickly sketched out. Well, if I was to provide you a completely honest commentary, then it would be to say that some of the lines are a bit to dark. Why don't you please do 28 seconds of 27 second faces and expressions? (27 sec + 1 sec faces and expressions) The reason why you could do this, so that your gestures would be less rigid, and more dynamic, energetic, and fluid.
My hat's off to you, and I hope you'll find this completely and totally informational and encouraging.
P.S. I recommend the Gesture Drawing app for iPad Pro.
Thank you for the suggestion. It is very helpful.
