Hi! First of all, congratulations on finishing lesson one!

I'll go over each exercise and give some feedback, if you're left with any questions don't feel afraid to ask.

Superimposed lines

To start off, there seems to be fraying on both sides on some of your superimposed lines. Make sure you take your time and properly position your pen at the starting point. This is so important to do because in order to make confident strokes, and thus lines, the right preparation is necessary.

Ghosted lines & ghosted planes

Overall these look good, but there's a bit of wobble. Keep practicing and eventually that'll go away.

Table of ellipses

The issue here is that you're drawing through your ellipses many, many more times than just twice or trice. The reason why it's recommended to draw through them twice/thrice is that it helps your draw quicker, with more confidence which then results in a smoother, more even shape. It also helps build muscle memory. On your first page, especially on the upper half, most of your ellipses are overlapping/going out of bounds. You want to make sure they are touching each other, but not overlapping. Make sure you're ghosting enough and when you feel confident draw it. Your second page looks better, with much less overlapping. Nonetheless some ellipses still go out of bounds/don't quite fit snugly within their boundaries, and I noticed you didn't draw through some ellipses. This will cause them to get more uneven, bumpy etc. It's better to draw through them twice/thrice as mentioned above. Nice improvement though!

Ellipses in planes

The same applies as above, make sure you try and draw your ellipses to fit snugly within their respective planes, and a number of them are wobbly. There's no shame in taking your time ghosting these! They are hard, but with practice they will definitely improve.

Funnels

The problem here is that you're not drawing minor axes, this is such an important step and can absolutely not be skipped.

Again, you're not drawing through most of your ellipses . The purpose of this exercise is getting used to fit your ellipses snugly in a set space, and getting used to the minor axis line which will be used many times in lesson 2. That's why it's imperative to do this exercise correctly. Had you drawn a minor axis line, most of these would've been done perfectly. As a reminder, you want the minor axis to cut an ellipse in two symmetrical halves.

Plotted perspective

Looking good, not much to say here.

Rough perspective

There's only one page of rough perspective, so I'm going off of that. Well done on the perspective! It looks like every line is going towards the VP quite well. Unfortunately this is hard to see, as you didn't use your depth lines and extend them toward the horizon. This is an important step in order to check your work. I see you also repeat lines, you should leave these alone, even if they are wrong. It only draws more attention to your mistake.

Rotated boxes

Your line work looks a lot better! The issue here is that you're not drawing through your boxes. The reason you want to draw throught them is so that you get to understand how forms sit and operate in space, by not drawing through them you're missing out on a lot.

Organic perspective

Make sure to start off with a darker line as it is closer to the viewer, and then gradually lighten your line as it goes further into space. Most of your boxes look (a tad) wobbly, so make sure to ghost as much as you need to.

You have done well, but there's some thing I would like you to do in order to fully grasp the concepts necessary to go into the box challenge and lesson 2.
