Hi Izaichan261102! I am Feldspar and I will be critiquing your work today. I hope you've been keeping up with your 50% rule and warmups while waiting! Lets start!

Lines

• Superimposed Lines: I see your lines wobbling a little. I suggest that you're hesitating and not quite giving up control.

• Ghosted Lines: I see your marks wobble a little. It can be a hint that you are executing your marks not from your shoulder but I suggest it comes from hesitation and focusing on their desire for accuracy. Keep an eye on this throughout your warmups.

• Ghosted Planes: I see some wobbliness here and there but there is nothing warmups cant fix. Remember dont rush and give time to every line. Don't forget confidence beats accurate!

Ellipses

• Tables of Ellipses: I notice some ellipses "float" on the page without any targets. Remember, ellipses need to have two borders that encase them, to check their accuracy. But i think it not a big deal as i believe it is about accuracy and will sort out itself with warmups, just keep it in mind. Try to keep ellipses in the similar row in similar orientation as much as possible.

• Ellipses in Planes: I notice some of your ellipses are a bit wobbly. Remember not to be too focused on fitting them against all four borders. But there is nothing some practice with warmups can't fix. Again Confident but inaccurate line > Accurate but wobbly line.

• Funnels: Good funnels. Try to vary size and shape of ellipses through warmups and optionally change the degree with every ellipse.

Boxes

• Plotted Perspective: I see most of the back vertical lines are not perpendicular. It's not a big deal as it is the result of all the little mistakes that accumulate as you work through core steps of this exercise. It means you have room to improve. Give yourself more time when lining up ruler.

• Rough Perspective: I see repeated lines! In DrawABox, you are not allowed to "fix" lines, you only have one shot at a line, and if you miss it, tough luck. This will force you to have a better planning phase, be mindful when ghosting, and will help your accuracy in the long run. Try to ghost more throughly when going towards the vanishing point, that may prove helpful.

• Rotated Boxes: You have a eye for rotations! Solid job.

• Organic Perspective: You are leaning more towards the dramatic foreshortening. I notice on the first page edges of your boxes are diverging or parallel to each other but on the second page it gets better! Edges start to converge correctly and you definitely understand the core principals behind this exercise. Although you boxes are generally the same size, shape and type of foreshortening :p. I believe with 250 Boxes Challenge instructions, you will understand and get better with Organic Perspective exercise even more and have plenty of time to experiment with boxes. Keep it up!
