Superimposed Lines

• The fraying at the end is quite strong, but that's something you'll improve on over time! It's important that you make broad shoulder movements and I think you did, good job.

• Some of the lines start accurately, but some have fraying on both ends. A large part of drawing is mentally preparing each line, be sure to focus on the prepwork! See: https://drawabox.com/lesson/1/9/fraying

Ghosted Lines

• Some lines are quite wobbly. You can fix this by speeding up your marks. Keep making the broad shoulder movements, and take your time practicing the moves before you confidently place down the ink.

Ghosted Planes

• Though still visible now and then, there's much less wobble here. Also you went creative with using the full paper space, that's great!

Tables of Ellipses

• A matter of practice. You did the exercise well, but the accuracy is still low. You're overshooting more than you're undershooting so try to correct yourself in that direction. Similarly for leaving gaps between ellipses now and then.

• That said, the exercise is about confidence, not accuracy, and the ellipses are properly shaped and quickly drawn, so you did this well anyway.

Ellipses in Planes

• These are a bit messy. Keep the confidence you had in the previous exercise :( over here you tried correcting a lot, trying to hit the edges rather than making good smooth ellipses. The latter is more important, the former comes with practice! See: https://drawabox.com/lesson/1/13/deformed

Funnels

• Same critique as the tables. Good looking ellipses, low on the accuracy, but that's okay.

• Pay extra attention to the precise angle you place the ellipses at. Some are slanted. See: https://drawabox.com/lesson/1/14/notaligned

Plotted Perspective

• No mistakes except for a small one at the bottom of the topright cube in the 1st frame.

• When hatching, try and be more consistent. Quoting the exercise: "You can also choose one of the front-facing faces of the box and fill it with some tight, parallel, consistent hatching lines that stretch all the way across the plane from edge to edge. Don't rush this or do it sloppily - it's optional, so if you decide to do it, make sure it's neat and tidy."

Rough Perspective

• Lots of wobbly lines, your confidence dropped here. Spend some more time ghosting and prepare for one fast, smooth line.

• I see a lot of do-overs. There is no harm in mistakes, either correct it by adjusting the next marks you place, or just let it be.

• Try and make sure all your parallel lines are actually parallel. Even though we're not using a ruler this time, most of the lines aren't actually guesswork, you can reason out precisely the shape the lines should have. See: You can also choose one of the front-facing faces of the box and fill it with some tight, parallel, consistent hatching lines that stretch all the way across the plane from edge to edge. Don't rush this or do it sloppily - it's optional, so if you decide to do it, make sure it's neat and tidy.

Rotated Boxes

• I'm afraid you didn't quite finish this exercise, some boxes are missing :(

• The front-facing faces of the cubes look quite good.

• The back-facing cubes are very hard to see, lots of overlapping lines and even worse. scribbles.

• The hatching doesn't help here, due to their random nature it's really hard to see what is intended and what is trying to cover up mistakes.

Organic Perspective

• Quite messy.

• Same as with rough perspective, after you've placed the initial Y, the rest of the cubes are no longer guesswork. You can reason out precisely the angle they are supposed to be at. See: https://drawabox.com/lesson/1/18/step3

• The lines here are wobbly too. Try and envision the mark you're going to place first, and take your time before actually putting your ink to paper so you can place a fast and confident line.

Overall

It started out really strong, but when it came to cubes things got difficult real fast. That's ok, especially rotated boxes and organic perspective aren't meant to be done correctly! However, they are meant to get your gears turning so you start thinking about spatial problems and how things relate to eachother. Consider reading those last two exercises again, more slowly, carefully thinking about which lines you can just place down, and which have rules you need to follow.
