Hi, I'll give you the feedback of the part you submit but this incomplete if you need help meanwhile your doing lesson 1 please use discord.

Lines:

So Superimposed Lines it's pretty well done except for one case where you have fray in both ends.

Next, Ghosted Lines your lines arch, thats mean your using your elbow and not your shoulder, a good idea to stop using it its to not give the elbow any point of contact with any surface, it'll be annoying but in this way you'll be sure you're using your shoulder.

And Ghosted Planes here you start to wobble that mean your not trusting in the ghosted line or you slow down when you see the other dot, I recommend to do ghosted line and be fast at this moment we don't care about accuracy I want to see smooth lines.

Recommendation, get A4 pages or a sketchbook but A4 it'll be helpful and take it easy, DaB its not a short sprint its a loooong race take a breath and complete the lesson 1. Good luck!! :)
