Hey Mangler,

Congrats on completing Lesson 1. Here are my thoughts on your submission:

Superimposed Lines Your lines are fraying a bit. This might be due to the pen though..

Ghosted Lines Slightly wobbly, but overall pretty decent line quality.

Table of Ellipses To much wobble. Remember to tilt the page to your favorite setting. And remember to draw from your shoulder.

Ellipses in Planes Planes are fine but your ellipses are deformed. I fear that you are obsessing over touching all edges instead of trusting your ghosting method. Better to overshoot all edges than loose confidence in lines (first eliminate wobble, than improve accuracy and consistency)

Funnels Not sure whether you understood the exercise. The further away you go from the center (the y-axis) your ellipses should be getting larger (keeping up with edges).

Maybe allow yourself some(just a little) elbow support, so your hand isn't completely in air, but also not fully fixed. This might make your lines more consistent. Maybe also try drawing on a tilted surface. And keep in mind to draw from your shoulder.

Rough Perspective The second page is much better, your line quality is also improving.

Rotated Boxes a bit messy but overall not the worst.

Organic Perspective best line quality I've see from you so far.
