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. The main problem with your lines is arching, 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. I've noticed that some of the back faces of your boxes are not rectangular. By rectangular, we mean that they should be composed of horizontals that are parallel to the horizon line, and verticals that are perpendicular to it. While this could also be caused by the sometimes inaccurate lines, it's worth mentioning that there should not be any arbitrary guesswork or random angles. Don't forget that these rectangular front/back faces are the unique characteristics of 1 point perspective.

On the other hand, I also saw a drop of your line confidence here. It's understandable and expected to be overwhelmed by the amount of information about boxes presented at this point, sometimes causing students to neglect their line confidence. Remember that boxes are just a bunch of lines.: plan your boxes, put down the dots, and ghost the lines one by one. When you're ghosting, only that line matters.

As the notoriously most difficult exercise in this lesson, you've done a pretty good job at doing the rotated boxes. You've used neighboring elements to deduce the next orientation of boxes, but I think you could've rotated them a bit more. It's very common for students to confuse rotation with convergence of the boxes, like this: https://imgur.com/a/gd10hkK. When rotating our boxes, at least one of the boxes' sets of parallel edges will have its vanishing point move - frequently it'll be two. If our boxes have the same vanishing point, then they're not rotating. (https://drawabox.com/lesson/1/21/notrotating)

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 & ellipses confidence. Again, congratulations and keep up the good work!
