Hi! Fried wontons sound so good right now... ^^

Congrats on finishing Lesson 1! I have issues with 3D perspective too. I think we all do. It's not an easy thing to put lines on a paper and imagine them as something other than lines on a paper! XD

One overall thing I noticed is that most things feel rushed. Your lines look sketchy or scratchy, instead of single, planned lines. Almost like pencil sketches. There are places where you've sketched over lines, or started and stopped and drawn another line. Your ellipses are better but similar, with some very light and only going around once and some are drawn through a bunch of times. Make sure you're taking your time with each point, ghosting, and planning each line, then drawing it once. With your ellipses, make sure you're planning and then only drawing through two or three times max.

Superimposed lines - Your second page is better. You have fraying at the start and end of your lines on the first page, so it feels more rushed.

Ghosted lines - You have so many points! ^^ I would have drawn more lines, since you have the points there. This also feels rushed, and you've got some curving in your lines.

Ghosted planes/Ellipses in planes - A few wobbles and arcs, but most lines are straight. It doesn't look like you plotted all of your cross points though, like you got to a part of each page and just starting drawing the lines. Make sure you take the time to plan each line before you draw. For the ellipses, most are okay, but it looks like some you just kept going until you touched all of the sides, even if it took a bunch of times around and meant shifting the ellipse over inside the plane. Drawing through is good, but doing too much to try and correct your mistakes doesn't really help you see where your issues are.

Table of ellipses - You did a good job keeping your ellipses uniform within each box and touching the edges. In some of the curved sections, your angle shifts. The second page is better. The first page is very sketchy, with some of them drawn through many times.

Funnels - Your ellipses are a lot better in these! They don't overlap edges too much, are the same angle and even, and are drawn through only twice. The ellipses on the outside should be wider than the ones in the center, and again you have that light sketchy look.

Plotted perspective - Good! Not much to say here. ^^

Rough perspective - These lines are very sketchy. Make sure you're plotting your points and planning and ghosting each line before you draw, then drawing only once. Take your time to line up your parallel and perpendicular lines with the horizon and sides of the page. Then ghost each edge to the vanishing point, plot a point, and draw a single line.

It also looks like you drew your grey lines from the corners to the vanishing point to show where the edges should have been instead of using a ruler to trace over your actual edge lines back to the horizon. https://drawabox.com/lesson/1/16/example See how his red lines trace over the edges from the front of the box to the back and then continue to the horizon? This will better show you where your lines are going, and where you struggle, so you can try to fix it.

Rotated boxes - This one was so difficult, right? Your boxes are spaced too far apart. If you keep everything close, you can use the lines of the boxes you've already drawn to help you draw the next one. Also, remember that as they get further away and turn further around that curve, they get smaller and more distorted. I don't see any plotted points on the outer ones, so it looks like you just guessed and quick sketched those in.

Organic perspective - I like your "no idea what this is" note. XD Again. I don't see clear plotted points and it seems like some of these lines are quick guess sketched in instead of taking time to plan them out. But for the most part you follow the line, with larger boxes going to smaller ones. Making this a little more drastic and drawing more boxes along the line will help you better imagine them as 3D boxes going off into the distance. Make sure you're starting with the Y method, then planning each line out from there. I actually found when I thought too hard about it and tried to envision the entire thing, I just got more confused and my boxes went wonky. Drawing the Y, then following each step and drawing in almost parallel lines from there helped me take it in pieces.
