Just some stuff to show that cartoons aren't the only thing you gotta draw to get better at artwork.
the first sketches are 2 minute foot and hand life drawing gestures. They are my personal favorite things to life draw.
then theres a perspective scene sketch thats unfinished, and a hour long portrait sketch from a photo, kinda off but it mostly shows how I render.
Then just a page that shows how I used "S curves" in my sketches, which are very messy but show alot of action.
