This is definitely an improvement over before. I'm pleased to see that your minor axis corrections are considerably more accurate, and that as you've worked through the set, the ellipses in your cylinders have gotten more accurate as well.

To your question about feeling like you need to practice more freehand ellipses, you're giving me the impression that perhaps you haven't been continuing to practice the exercises from previous lessons as part of your regular warmup routine. You are expected to be doing so, as described back in Lesson 0. The few pages we do in the lesson are not intended to develop any kind of mastery. Instead it's just to give us a body of work we can use to assess what you do and don't understand, so corrections/advice can be offered before you continue to do those exercises on your own.

Now, as you move forwards you'll find that starting with Lesson 6 we encourage students to pick up ellipse guides - at the very least, the master template listed here (a full set of ellipse guides can get pretty expensive, whereas the master template has limited size options but a full range of degrees, which is good enough for most of our purposes here). This is because drawing ellipses is hard, even for those who've continued practicing them alongside the rest of the lessons. Since the last few lessons rely on them a great deal and themselves are complicated, the use of an ellipse guide can help us to focus on the new things we're learning, rather than being distracted with the things we've already been over. Definitely consider picking one up.

I'll go ahead and mark this challenge as complete.
