Hi CertainElf! My name's Flippy and I will be critiquing your submission today. Let's get right into it!

Superimposed Lines Exercise

Your lines are looking good. There is a minor amount of wobbling, but this will go away with mileage.

Ghosted Lines Exercise and Ghosted Plains Exercise

Your ghosted lines and ghosted plains look very on-point with minimal wobbling and barley any overshooting/undershooting. Nice work! The intersections of the plains are especially well-centered. 

Tables of Ellipses Exercise

The ellipses of the largest degree are a bit wobbly at times. Always prioritize confidence over accuracy, as your accuracy will improve over time. Consider ghosting over your ellipses more before committing to the page. Also remember to limit the number of passes over your ellipses to 2-3 times (preferably two). https://d15v304a6xpq4b.cloudfront.net/lesson_images/a76a8906.jpg It appears you have already been doing this. Keep it up!

Ellipses in Plains Exercise

This can be a tricky exercise. Some of your ellipses don't quite reach all four edges of the plains, but it's fine. Most of them are well-placed. Keep working to tighten up those passes!

Funnels Exercise

Most of your ellipses fit well into the boundaries of the curves, as well as being evenly centered on the minor axis. In the future, I would encourage (though it isn't required) further experimentation with the shift in degrees between ellipses, starting at the narrowest in the middle and expanding out to a full 360 degrees on the ends. I can see you are already doing this to an extent. Also remember to find a comfortable orientation to the page when drawing ellipses. (Or lines, for that matter!) Good job!

Rough Perspective Exercise

Your rough perspective looks good. There's some deviation from your target vanishing point in your first panel, but then in every panel following your angles are much more precise, so I can see you got the hang of it.

Organic Perspective

Once again, on your first panel, the convergences of some of your boxes are a little wonky, but then in every panel after you really nailed it. Not all of them are perfect, but this exercise is all about estimating convergences toward suggested vanishing points, so good job.

Rotated Boxes Exercise

And finally, the rotated boxes. Now, this exercise is supposed to be difficult, and you did a great job with it. The overall form is slightly off-centered in relation to your guidelines. The shape of the form isn't quite a sphere as in the example homework, but as this exercise is teaching us to go off of the existing elements of a drawing to estimate comparatively how each box's parallels converge towards its own vanishing point, it makes sense that little deviations would compile on top of each other, resulting in a slightly warped sphere, but nonetheless accurate. I also like your use of hatching lines, they came out very clean and make the drawing much more readable and believable. Good work!

Overall

So, for your submission overall: your lines look great; your ellipses are coming along, but could use more practice. I would suggest adding some of the ellipse-based exercises to your daily warmup until you are more comfortable with them.

You're probably sick of hearing me say this by now, but you did a really good job with this first lesson. I noticed you haven't included the Plotted Perspective exercise, and I assume that's because you have already worked through Lesson 1 before (as you mentioned you started over) and understand how to work with vanishing points. If you have not previously completed this exercise, I would advise you do so, and submit it in a reply to this critique.

Good work!
