Hello! Good job finishing the lesson. Let's get it critiqued!

Starting with the lines

Superimposed lines No fraying at the start point, which is good. Some wobble, which can be helped by being more confident when drawing the line. Focusing on the end point may help too.

Your Ghosted Lines&Planes are great. Very little wobble, which will improve with more mileage, although it always helps to stay confident in your execution over accuracy for now. I see no issues in Ghosted Planes that weren't present in Ghosted Lines, which makes me think you took your time with the exercise. Good job!

Moving on to ellipses

A fine Tables of Ellipses. You drew through the ellipses and made sure to try and fit them within the borders and against each other. Fairly smooth and even shape on average, although they sometimes become stiffer and deformed in Ellipses in Planes. This can be helped by reminding yourself that a smooth, even shape confidently executed from the shoulder is more important here than fitting the ellipse inside the plane and touching all four sides.

Good job with the Funnels, drawing through your ellipses and placing them snug against each other and the funnel sides. I'm noticing that some aren't aligned with the minor axis. You want to make sure that the minor axis cuts each ellipse into two equal, symmetrical halves, down their narrower dimension, as mentioned here in the course.

And finally, boxes

Plotted perspective is done correctly. A few of the back edges are slanted, which is expected and can be mitigated with taking your time to align the ruler.

Excellent Rough Perspective. You did well in keeping the faces of the boxes rectangular and extending the depth lines to the horizon line. Your linework remains mostly uncompromised by the increased complexity of the task, keep it up!

A solid attempt at Rotated Boxes. You did well by doing the core setup, drawing through the boxes, applying rotation fairly well and trying to keep your gaps tight and consistent. All required boxes are present as well.

In Organic Perspective I'm seeing good rotations and scaling with depth and no leaning into dramatic foreshortening. However, there are a few problems with this exercise. First off, some edges seem to be diverging rather than converging towards their vanishing point. Revise this part of Rotated Boxes exercise for help with your convergences. About that box marked with a question mark where only two sides are visible (it's not the only one like that, too): it turned out like that because you didn't do the Y method correctly. As you can see, your initial Y is more of a ? shape. Quoting the lesson instructions: "The lengths of the various arms [of the Y] is up to you, but do make sure that the angles between them are of at least 90 degrees - when the angles get smaller than that, things tend to get a little... weird."

In conclusion: A very solid submission, with some struggling in the Organic Perspective part. Still, I believe you've learned well, and with keeping provided feedback in mind, you are ready to move on to 250 boxes and iron out the kinks there, together with warmups.
