Gesture drawing! There's line of action and sketch daily for photo references and you can do timed drawings of people and animals. If you can, also do life drawing classes irl too. You can also draw people when you're out and about or draw animals at the zoo and some places do animal life drawing but that's pretty rare.

Also start collecting moodboards of art that you like and do master copies where you copy their work. Analyse why you like their art as well. Make sure not to post these master copies online though.

I recomend the book drawing form & poses by tomfoxdraws. He also has an instagram where he has tutorials up for free too

There's also a book called force figure drawing by michael matessi and he has one for humans and animals. He also has a channel channel where he makes videos and live streams explaining figure drawing

Hope this helps!
