Hey there! Congrats on finishing lesson 1.

Superimposed lines: I think they look good. You are very confident in your strokes, and I see minimal wobbling. One thing I do see a little bit of is fraying on both eyes. This doesn't happen a lot, but keep in mind to make sure you are starting at the same spot when doing this exercise.

Ghosting Lines: Once again, excellent work on confident strokes. While there are instances where you miss the dot, that is no problem at all. In fact, I was just doing the exercise today as warmup and still miss the dot occasionally. The main goal is to have confident strokes, and you are doing well with that.

Ghosted planes (and ellipses in planes): These look fine as well. You took care to only draw through ellipses twice or thrice. The lines look mostly confident, too. There are some instances where the lines wobble, so make sure to keep your confidence and draw from the shoulder.

Table of Ellipses: You did a wonderful job on confidently drawing through your ellipses. You also did well in varying the degrees of your ellipses, and you can push it even further. One thing I notice is a lack of very thin degree ellipses, such that you can fit ten or more in one cell. In future warmups, I would do that, as well as practice more wider degree ellipses (essentially circles).

Funnels: Great work on this exercise. Your ellipses look confident, and you made sure that the center line split all the ellipses in half. One thing I did notice was that there were occasions where the ellipses were either spaced out slightly or they went overlapped into another ellipse. This will improve over time. Just make sure that in future warmups, you have the ellipses tightly close to each other.

Plotted Perspective: The boxes look pretty solid here. You made sure to draw from the vanishing point, and the lines look confident. One thing you can do to push yourself further is to add line weight to the boxes after you finish connecting the lines. This will come up later in Drawabox, but it is very important to distinguish the main figure from all the background. That way, the viewer has an idea of what to focus mainly on. Also, adding hatching lines can help gain an idea of perspective, so feel free to do that if you want.

Rough Perspective: Like you said, this exercise feels like it takes a lot a guess work. I still wouldn't say that I'm the best with it, but it does help as you go into the 250 box challenge. Make sure that you are still confidently drawing the lines. I noticed that there were more instances of wobbling in the lines making up the boxes. Also, make sure to plot back to the horizon for all your boxes. I'm assuming on the first page of the exercise you forgot, since you did it on the second page. Just remember that this gives you an idea of how your estimate of perspective is. Overall, nice work on doing this exercise.

Rotated Boxes: I think the final product looks great. This is definitely a challenging exercise that once again makes you focus on perspective. Continue to be confident in your line work. Also, make sure you are drawing through all of your boxes. There are a couple of boxes on the lowest level that are incomplete.

Organic Perspective: You nailed this exercise. Your line work looks mostly confident. I get a good sense of scale with how you vary the sizes going into the page, as well as how you overlap boxes. Keep up the great work.

Overall, I think you are ready for the 250 box challenge. The challenge will...well, challenge your way of perspective. I would suggest doing the plotted perspective and rough perspective as warmups for this challenge, but make sure to keep all of these in your back pocket. Good luck!
