Hello, congratulation on finishing lesson 1. I'll be only pointing out the thing that needs to be improved and Here are my observations:

  1. Superimposed Lines

The only issue I saw here is that a lot of your line has stray on both end, so make sure to taking the time to position your pen correctly at the starting point of your guideline.

  1. Ellipses In Planes

Take your time to ghost your ellipses before executing them because I see a lot of your ellipses feel wobbly, You should submit the homework for ghosted planes and ellipses in plane separately, so it's much easier for me to check your homework.

  1. Funnels

You're doing good in this excercise, Try to get the degree of your ellipses to increase as you move outwards from the center.

  1. Rough Perspective

Make sure to take your time to ghost the lines before executing it because I see some of the lines feel wobbly,

  1. Organic Perspective

This is just a suggestion, establish your box hierarchy by adding line weight so it's much easier for me to check your homework.
