Hi Lead! Here's some feedback for lesson 1.

A quick skim of your exercises and it appears to be promising.

Lines - Superimposed lines are good. One thing to note is that for a couple of the swirls and a couple of the lines, there seems to bit a bit of fraying at both ends but it's not too bad. Remember to take your time to carefully place your pen on the starting point before executing your line. Ghosted lines look great. Very confident strokes. There are a few that have a very slight arc and this can be remedied with drawing more from your shoulder pivot or arching towards the opposite direction with your pen. Ghosted planes look good too.

Ellipses - Great that you spotted lines out of bounds! Overall, I think you did well. The angles seem consistent through each box. On the first page there are a few that aren't completely drawn through twice and there is one ellipse at the bottom left where it was attempted a second time. On the second page, there seems to be some ellipses that have been drawn through more than three times. The ellipses in ghosted planes look good too. Not too many out of bounds. Keep in mind to draw through your ellipses just 2-3 times. For funnels, I think there is a good gradual change in size outwards from the center.A little too much overlapping for the ellipse in the funnel in the center of the page but the rest are fine.

Boxes - Plotted perspective looks great! Very good attempt on rough perspective. Note, some lines have a little bit of arching.

Rotated boxes is challenging but I think you made a very good attempt at it. The middle row and middle column rotate well. I think most of the boxes are rotated well. It's very subtle towards the outer corners but they rotate--some ever so slightly. Overall, organic perspective looks great. Good gradual change in size. Some lines seem to be repeated again but not sure if it's to thicken the outline or correct the line. Note, do not repeat a line unless it's to thicken the outline, otherwise, keep going.

Congrats on completing Lesson 1! Don't forget to use these exercises as warm-ups. I recommend the ellipses table focusing on drawing through 2-3 times and ghosted lines to straighten out wobbliness and arching.
