I took a look at your submission and described what stood out to me most. I'm currently working on Lesson 4 myself.

The primary thing for you to focus on is confidence and smoothness in your lines. It's a core concept that will be used in all future lessons. Wobbly lines are present throughout your submission and it's important that you have a more firm grasp on the concept of smooth lines before moving on. Here is a link to the relevant section on the lesson page. You don't have to be perfect at it at this stage; you'll be working on improving this area as well as things like line accuracy throughout the course. Consider the three levels of this exercise. Your ghosted lines page is sparse and I think the concept is important enough to warrant another attempt. Here's a picture I took from a section of one of my warmups. You don't have to make your attempts this close together or all horizontal like this, I just wanted to give an example from someone who has progressed through the lessons a bit even if I'm still improving my own markmaking still.

Your funnels exercise suffered as a result of wobbling as well. It will be more productive to try constructing ellipses around solid foundational lines. Review this step. There's also a consistent amount of tilting to many groups of ellipses. Establish your axis lines with a ruler, and do your best to line up the ellipses with them. Here's a link to the alignment section of the exercise.

I'm requesting revisions for your submission. Read through the relevant pages and/or watch the videos for the listed exercises and give them another attempt.
