Okay, these look better in terms of drawing through your ellipses. You are still having issues with getting wobbly linework and deformed ellipses because you are overly concerned with accuracy and are slowing down your stroke to compensate. Although accuracy is our end goal you need to focus on smooth confident ellipse shapes first by making sure you always ghost your ellipses multiple times and then try not to slow down your stroke while making your actual mark. The hesistation while slowing down your stroke for the sake of accuracy is why you are getting deformed ellipses and line wobble. Try and rely a bit more on the muscle memory you build up while ghosting and almost make your mark without thinking. This will be less accurate at first but should lead to a smoother overall shape that doesn't have wobbly linework. You'll build up accuracy with consistent practice. So keep these tips in mind and keep practicing ellipses during your warmups. I'm going to mark this as complete and you can move on to the 250 box challenge.
