Hello Archiexanth, congratulation on attempting the Lesson 1. I am not sure if it is intentional or a mistake(either from the upload side or of my internet), but your link contains only one image, which is a single page of Superimposed lines exercise.

In the one page of Superimposed lines, your lines are confident and with little to no fraying from the beginning point, so thats really a good starting point.

If you have completed all the exercises from Lesson one, do make sure to upload them in a single tumblr link! Good luck and looking forward for your future uploads.
