Excellent occupation, Lauabaloni, excellent occupation on your 30 second expressions and features, yet, I've got one very, very, very much, much, much, much, much, much smaller suggestion: Would you like to do 1 minute of 29 second sketches of faces, if you please?? The reason why, is because, your facial features will become more gestural, fluid and looser, and lively. Hope it'll be essentially beneficial into your warm-up drawings.
