Greetings, ExpiredSnow!

I'm here to take a look at your submission and hopefully give you useful feedback and tips on how to improve even more. I'll split my critique into three majors categories - them being Lines, Ellipses and Boxes -, and at the end I'll give you a broader comment about the entire lesson.

Critique

Lines

Starting with Superimposed Lines. Your lines are frying on one end, which for now, is OK. Still, they're frying quite a lot. One tip that helped me fix this problem is to look at the second dot and not at the tip of the fineliner. The lines themselves are arcing a bit or are wobbly (especially those curved ones).

Moving on to Ghosted Lines. Your lines are arcing a bit here too. Remember that confident lines is more important than accurate ones. Do you remember the levels that were explained at the instructions? Level 1 is one confident line that doesn't pass through dot A or dot B. But it still is a confident/straight line! Always aim for confident lines. You should also reread the arcing lines mistake from the instructions. It should help you fix that problem.

Finally, Ghosted Planes. It would have been nice if you had taken a photo of the planes before you drew the ellipses but it isn't a big problem. Your lines are starting to look more confident. They're arcing less here. There's a bit of overshot lines here and there. One thing that should never forget is that each line has to be ghosted, in other words, you have place the starting and ending dot in order to use the ghosting method correctly. On the cross, you didn't place dots to ghost your line.

Ellipses

Let's move on to Table of Ellipses. Your ellipses aren't too bad but there is definitely room for improvement. You should always draw through your ellipse two to three times (preferably two times), no more or less. You followed this rule for the most part but there still are some ellipses where you did more than 3 rotations. Another thing that I need to point out is that your ellipses are wobbly a lot. Yet again, confident is more important than accuracy. It's true that the objective of the exercise is to have ellipses that touch all 4 sides of the frame without overlapping other ellipses but don't sacrifice all of your confident lines for that.

Then we have Ellipses in Planes. To be honest, everything that I said on the previous exercise also applies here. The only thing that I can add is that some of your ellipses look better here (especially on the second page).

Lastly, Funnels. your ellipses are looking even better here. There are some that have a pointy end that you should definitely avoid doing but besides that it looks great. On the 3rd funnel of the second page, your minor axis doesn't cut your ellipses in two perfect halves because the line isn't centered.

Boxes

Now, Plotted Perspective. Good job overall. I would just suggest to add a bit of line-weight and hatch one of the visible sides of each box to help clarify the boxes as explained on the step 8.

Moving on, Rough Perspective. Your guesses were more or less accurate for the most part. Your extended lines usually stopped near the vanishing point which is great. Remember to be patient when extending your lines. You overshot some lines - they should stop exactly at the vanishing point. Another thing is that the lines that aren't going to the vanishing point should be parallel or perpendicular to the vanishing point. This task becomes a lot harder to accomplish when you mess up some earlier lines of the box... Just keep that in mind. Also, most of what I said so far about lines also applies here (arcing lines, wobbly lines, etc.)

Going on to Rotated Boxes. This exercise is tough! It was for me, it was for you and it is for many other students. As explained on Lesson 0, we shouldn't grind. The major problem on your first attempt is that you made the back side of the box TOO SMALL. Besides that, you were doing mostly right. On your second attempt, you were doing even better because the back side of the box isn't as small as on your first attempt. You only had to draw the inner lines (the lines that we can't see) of some of the boxes and you would have 1/4 of great boxes!

And finally, Organic Perspective. It looks mostly alright. It is a bit too cluttered with that many boxes (nothing wrong with that!) but some clever line-weight would have done wonders. I have here a little guide on how to apply line-weight to this exercise. Take a look! One mistake that you repeat quite often is that your initial Y had an angle smaller than 90°. All angles should be greater than 90°as explained here. If you break this rule, your boxes will look distorted. This is explained more in detail on the Additional Notes Section.

In conclusion

Congrats on finishing the lesson! You've improved a lot since the beginning of the lesson but there still are many areas where you need to improve. As I said multiple times throughout the critique: Confidence > Accuracy

Never forget this! Remember to do warm-ups every day, as explained here (from Lesson 0), and focus on your current weakest skills - being lines.

Good luck on your journey!
