Hello Meedge, Congratulation! You make through all exercises. Here is my critique for all lesson 1's exercises:

Superimposed Lines: You did a decent job on this exercise. I noticed some of the lines are fraying at the starting point, which you need to be careful though. While it is fine to draw the lines fraying at the end for the first time, but when you do as a warm ups after you move on to another lessons, try to smooth out the line as well. I also noticed a bit of wobbly lines, especially on arch lines. Remember to use the ruler for the first line~

Ghosted Lines & Planes: You've done a good job on these. Make sure you don't repeat the lines and avoid wobbly lines, as I notice it on your ghosted lines exercise.

Tables of ellipses & Ellipses on Ghosted Planes & Funnels: The common mistake that I find in ellipses exercise section is you have drawn very VERY WOBBLY ellipses. As you may know the rule on drawing the lines in general, you need to put the confidency and smoothness at priority first, then the accuracy at last. I guess you are not very used to draw with shoulder. Here is the video for a reminder: https://www.youtube.com/watch?v=0_AdsK8x9Lw(https://) Also recap the whole ellipses lessons in general.

Boxes : You've done a great job at plotted perspective, rough perspective, rotated boxes & organic perspective! Just to remember the lines, as I previously mentioned the problem of it.
