Here is my critique:

So the main thing I noticed was the lines; while you've done a good job of using guide dots and stopping each line at it's destination, many of them look wobbly, especially later on in the rough and organic perspective sections.

Make sure to prioritize confidance over accuracy here, a straight line that misses it's target slightly is better than a wobbly one that perfectly connects two points. Make sure to carefully read the instructions for ghosted lines and remember to apply them in later sections.

Ellipses and Funnels look good; though the small wobbles might mean you should be going faster with those too.

For rough and Organic perspective: Apart from the lines being wobbly it looks like you did them properly.

For Rotated boxes, you're missing several boxes. There should be 25 boxes but you've only drawn 20. You're missing 2 on top, 2 on bottom, and another below the top on the right.

Here's reference for what it should be looking like (obviously not as high quality however) https://d15v304a6xpq4b.cloudfront.net/lesson_images/9a2db6a0.jpg

Don't worry too much about it looking good, rotated boxes is supposed to be difficult. The important thing is that you finish it.

(Full disclosure: This is my first time critiquing, and I've only just finished lesson 1 today; so keep that in mind!)

Lines

• Superimposed Lines: These all appear confident with a tight originating bundle that only frays at the end. I can't see any wobbles, good job.

• Ghosted Lines: These all look fairly confident and accurate, with ghosting beginning and ending points used for all lines.

• Ghosted Planes: A few wobbles here and there, your lines are very accurate but I wonder if you are sacrificing some confident straight lines to land precisely on your target?

Ellipses

• Ellipse tables: You do a very good job of just barely kissing one elipse to its neighbor, but quite a few go out-of-bouds of their container box, usually on the top line. They are drawn confidently and you drew quite a variety of elipses.

• Ghosted planes with elipses: You do a better job here keeping the elipses within the planes, and while there are some wobbles here or there I think this is a good job

• Funnels: Ellipses are generally split symetrically, they do not appear to be as confidently drawn as your table of ellipses, with more wobbles.

Boxes

• Plotted Perspective: This looks really well done to me.

• Rough Perspective: Vertical lines are perpendicular to horizon and horizontal lines are parallel, nice job. Your corrected lines are easy to see and generally on target, with a few oddballs here or there. When the boxes got far away from the vanishing point but had a very narrow angle towards it, often had the most difficult time in judging those angles. I like that you attempted a lot of big boxes in this exercise.

• Rotated boxes: Your boxe row that goes vertically up the page don't rotate as much as the horizontal row. The corners of your boxes are all kept very close together per the instructions which is good.

• Organic Perspectives: Something I struggled with too was keeping the line weight light for the small and distant boxes. For whatever reason my fineliner likes to drop a lot more ink on my tight short lines, so my lineweight was typically the opposite of what it should have been - the small distant boxes were heavy and dark and the big boxes were light and faint. Boxes have decent perspectives, and I really wanted to commend that big box in the second to last panel, it is really amazing. I think you have a good variety of boxes with different rotations and angles.

I think you did an excellent job overall and made a clear and thoughtul attempt to follow the instructions as they were written. The only thing that stood out to me is that in general you may be focusing a little too much on accuracy of a line ending precisely at a point, and this is leading to some wobbles that don't need to be there. Thanks for baring with me on my first critique and I hope it was somewhat helpful.
