Welcome and congratulations on finishing the first lesson of Drawabox! I'm Mada and I'll be taking a look at your submission.

Overall you did a great job here, but I do have a bit to mention so let's break them down one by one. I'll write the most important things in bold.

Lines

Starting with your superimposed lines, these are looking good. Ghosted lines look correctly ghosted and confident too. You've also demonstrated the same confidence in your ghosted planes with a great accuracy. However, I noticed that you didn't put the start and end points when you bisect the planes horizontally and vertically. This results in floating lines, like this: https://imgur.com/a/Ud2O6tR. Do not forget to always plan your lines first when ghosting, even though you already kind of know where they should be.

Another problem with your lines is arching and curviness, which can also be seen both in your ghosted lines and planes. This is a common issue that can have many different causes. At the end of the day, our brain does have to make certain corrections for the fact that all of the pivots of our arm (wrist, elbow, shoulder) result in an arc rather than a straight motion. So, while the pivot you do will most likely result in an arc, you have to correct them consciously so it becomes straight. Make sure that you ghost while pivoting from your shoulder, try to intentionally arc your lines to the opposite direction to counteract the natural curve. This constant correction you make will eventually become natural as you get more practice. Read more here: https://drawabox.com/lesson/1/ghostedlines/arc

Ellipses

Now with the tables of ellipses, you've demonstrated a great understanding of the concept in executing confident ellipses. The ellipses in planes are nice, you drew it confidently and snugly in their respective planes.

The funnels are also looking great; you've managed to fit them snugly and aligned to the minor axis and carried the same confidence as in previous exercises. I have no complaints here as your ellipses will tighten as you get more practice. Also this is optional, but you can attempt the optional step of varying the ellipse's degrees as you move outwards in your warm ups, as mentioned here: https://drawabox.com/lesson/1/18/step3

Boxes

You've shown a good understanding of how to make 2 point perspective in the plotted perspective. I did see some skewed back vertical lines here and there, which is usually caused by an accumulation of human error as you plot more and more lines. I assume that's the case and you understand that every vertical line is straight in 2 point perspective. Even if the points are not aligned correctly, try to find a middle ground and draw it as vertical as you can.

You've applied the ghosting method and lines extension correctly for the rough perspective. You also drew the front/back faces rectangular, which is correct for 1 point perspective. Aside from that, I can still see a little bit of wobbles in your lines at this point. You might still be hesitating here, or limiting your pivot for some reason (usually by unconsciously using your arm or wrist as the pivot instead of your shoulder). Do keep reminding yourself to use your shoulder, and prioritize confidence over accuracy. They will get better as you get more practice, but you do need to keep conscious of what you're doing right/wrong and tweak it accordingly on your next attempt.

As the notoriously most difficult exercise in this lesson, you've done a great job at doing the rotated boxes. You've rotated them pretty well (while making sure to move the converging lines) and used neighboring elements to deduce the next orientation of boxes, which is the whole purpose of this exercise.

Finally, organic perspective looks great as well. They look like they belong in the same page and the lines converge as they move farther away from the viewer. There are a few hiccups here and there where there are divergences that results in skewed boxes, but overall they're minor and they look pretty solid.

This will get more relevant as you get to the box challenge, but any hatching from this point on should also be done with the ghosting method. It will make your stuff cleaner and more practice is always good! Try to cover the whole area of the box with consistent spacing.

Anyway, I think you've grasped the concepts of the whole lesson and ready to put them into practice in warmups. Remember to keep working on your lines confidence as they are the weakest part of your submission so far, and your drawing will surely benefit more if you can get straighter lines in your boxes. Again, congratulations and keep up the good work!
