Hello! I'm Joxmarf and I will be reviewing your Lesson 1

Superimposed Lines

There's some fraying. Remember to place your pen mindfully before doing the stroke.

Ghosted Lines

Well done.

Ghosted Planes and Ellipses

Woah, this one is pretty good! Your ellipses are tight and drawn with confidence.

Table of Ellipses

Some of your ellipses aren't complete. I assume you are using ballpoint for these? Don't do the strokes light enough for the marks to not appear on the page.

Funnels

Well done.

Plotted Perspective

Well done.

Rough Perspective

Be careful with you line extensions. Some line extensions lean to no place at all. Remember the line extensions come from the lines of the boxes converging towards the vanishing point.

Rotated boxes

Well done.

Organic Perspective

Your boxes have a dramatic foreshortening. Having a shallow foreshortening would help keep the sense of scale consistent. Also, be mindful with the line weight. You add heavy line weight on some of the boxes which are farther away. It breaks the sense of 3D space.
