1. Super imposed lines

Looks great. Lines look confident which is key to lesson 1. Accuracy should improve over time as you practice more!

2. Ghosted Lines

Wow, well done. Lines seem very confident and smooth for the most part, AND you seem quite accurate too!

There was some slight wobbliness on the left most line, but overall you did great!

3. Ghosted planes + Ellipses

Slight wobbliness in some of your planes, remember smoothness is prioritized over accuracy. With that being said though, most of your lines are smooth so good job.

Ellipses are also done well; they are smooth. They break out of the planes' bounds slightly, but this should improve over time.

4. Table of Ellipses

Noticed some of your narrower ellipses are a bit tighter on one end of the ellipse compared to the other end. But I believe so long as you continue drawing through your shoulder, this should be sorted out over time.

Also make sure that all of your ellipses within a set are touching each other.

They slightly break out of bounds too, but again with practice I believe this will naturally improve.

5. Funnels

Good work on the funnels. I noticed some wobbliness in the center (aka most narrow) ellipses.

But as your ellipses get bigger, your smoothness improves. Be sure to practice your narrow ellipses more so that they can come out as smooth as your larger ellipses.

For the most part, you've successfully cut the ellipses in half as well. Nice!

6. Plotted Perspectives

Looks good, nothing wrong here in my opinion. Nice!

7. Rough Perspective

Slight wobbliness/shakiness in your lines. Make sure to draw the lines of your boxes more confidently.

Other than that, this looks good.

Your vertical and horizontal lines are nicely perpendicular to the horizon, good job.

8. Rotated Boxes

Nice work. Your line confidence/smoothness is well done here.

The most outer boxes (at the end of the horizontal and vertical axis) should be rotated a bit more in my opinion.

9. Organic Perspective

Nice work!

Line confidence is strong here.

The varying sizes from largest to smallest (aka closest to farthest) can be see here too.

Not really a critique, but I think you should experiment with drawing some of the boxes behind the previous box. (e.g. box 1 partially overlaps box 2)

1) Super-Imposed Lines

Both pages have confident, unwavering lines which was the key to the first exercise. There is a noticeable curvature to the lines drawn, but that can be fixed. Looks great!

2) Ghosted Lines

Much of the curvature from Super-Imposed Lines seems to be gone in this exercise. This is a really well-done exercise. It's just a bit of a shame that there's a bit of ink bleed from another exercise through the page, causing some initial confusion as to where your points were plotted. I don't see any other problems with it though.

3) Ghosted Planes + Ellipses

I can say through my own recent experience that ellipses are really difficult to draw, so even though they may appear messy to the naked eye, this is a really good job for a first attempt at containing ellipses in boxes. As for the boxes that contain them, the wobbliness from 1) seems to have returned at some points, most noticeably with

this box here. Besides the curvy linework at times, not a bad attempt at all.

4) Tables of Ellipses

There is a noticeable amount of space between the first two circles, with space empty space existing in smaller amounts in various other parts of the exercise. Consistency is a difficult thing to get right with circles and ellipses, so for the most part this can likely be excused. Overall a very well-done piece of work here.

5) Funnels

I don't have any particular gripes with this one. I'd have to agree with Bobbee with the slightly scrunched middle ellipses, but besides that I don't think anyone could say anything bad about this one. Very nicely done.

6) Plotted Perspectives

Yep, agreeing with Bobbee here, too. Very clean.

7) Rough Perspective:

Your boxes are clean for the most part but there's definitely a noticeable mistake here in the first page. Mistakes are annoying but since you're using fineliners, trying to correct them only makes them more obvious. Very nice work on the trajectories, however; they're very close to the vanishing point.

8) Rotated Boxes

Ah, the "challenge" exercise for this lesson. All the lines are very clean and the extra touch of shading is nice and gives it some nice depth. This was supposed to be a difficult exercise and you seem to have completed it like it was nothing. This isn't a criticism, but the only thing I noticed was that one of the sides was missing the hatching that the rest of the boxes' sides had. Amazing work, though!

9) Organic Perspective

Very clean lines and very well done maintaining the perspective here. Like Bobbee said, though, I can definitely see a lack of overlapping boxes in this exercise, which Uncomfortable cited as one of the things he really wanted to see in this exercise. This box on the second part of the first page is a bit large compared to the ones before it, though. This is the only one of its kind, though. Very nice work!
