Hey there! Congratulations on finishing Lesson 1! I’ve looked at your submission and have a few pointers that might help you out. I’ve divided my feedback according to the exercises:

Lines:

Superimposed Lines:

You have done a good job drawing often enough on top of each line and they look very smooth and confident. Sometimes there seems to be some arcing, but that’s okay for this exercise. Rarely there is some fraying on both ends of the lines, especially on the curves. You can avoid that by being more conscious about where you put your pen down each time you draw on top of a line and not rushing it.

Ghosted Lines & Planes:

These two are pretty similar. Most of your lines in the Ghosted Lines exercise are smooth and consistent, only some are wobbly or arcing. In the Ghosted Planes exercise, however, your lines are a lot more wobbly. You can avoid the arcing by making sure you draw from your shoulder. Or, if you are already doing that and there’s a natural arc to your lines, try to arc in the other direction consciously and they should turn out straighter. The wobbly lines can be avoided by making your marks with more confidence and/or taking more time ghosting before putting your pen down.

Ellipses:

Table of Ellipses:

You’ve done a good job drawing through your ellipses twice every time, and most of your lines are smooth and confident. Also, it looks like you’ve been drawing them with a concrete goal in mind. Most of the time they are touching each other as well as the corners. The only thing I noticed here is that sometimes they are not touching the left-most border. You might want to pay special attention to that if you do this exercise in your warm-ups.

Some of the ellipses are also a bit misshapen, taking a little more time ghosting them, might help you there.

Ellipses in Planes:

They are all smooth and confident. Most of them are at least touching three corners, which is a great start. Well done!

Funnels:

The ellipses are well aligned to the minor axis and mostly snug against each other as well as the border of the funnel. A few times the ellipses don’t touch at the shorter lines (the ones dividing the minor axes) and at some points, they don’t touch the edge or cross the border. But that’ll get better over time. Just pay special attention to that in your warm-ups. Overall, well done!

Boxes:

First of all, I noticed that all throughout the boxes exercise your lines are starting to get a lot more wobbly compared to the earlier exercises. You seem to prioritize accuracy over smooth, confident lines. Try to plan your lines by marking them with a dot, ghosting, and then making a confident mark. Don’t be afraid to make mistakes, it’s okay. With time you will become more accurate.

Plotted Perspective:

All in all, well done, but you might want to look at the box in the middle of the last compartment again.

Rough Perspective:

You did a good job trying to keep your horizontal lines parallel and the verticals perpendicular to them. However, you plotted your extension lines back to the vanishing point. Instead, you should extend your own depth lines back to the horizon line to see how far off you were. Here’s Uncomfortable’s reasoning for that:

There's a good chance that you'll find them not intersecting with it at the vanishing point, and you may also find that the further away your boxes are from the VP, the further off they are in their alignment. This is totally normal, and it helps a great deal to go over our work in this manner to help identify where our estimation of perspective tends to drift, so we know what to focus on during our next attempt.

In your pictures, it looks like you might have used a pencil for extending the lines. A good idea might be to erase them and then extend your own depths lines. If not you might want to take another colored pen you can differentiate from the one you used and then extend them.

Rotated Boxes:

You did a good job drawing through all your boxes. However, there are two things that stand out here. First of all, some of your boxes aren’t rotated but converge toward the same vanishing point. Especially the ones on the outer edges of the axes. Secondly. You’ve done well keeping your boxes snugly together in the lower left segment, but not in the others. The gaps are supposed to be narrow on consistent. That helps with figuring out the direction and rotation of the boxes, so you don't have to guess as much. There should be the same amount of boxes in each segment as in your lower left one. Also, be mindful of your hatching. Only add it to the sides of your boxes, not between them.

Organic Perspective:

Overall you’ve done a good job here, too. The boxes are getting smaller the further away they are and most of them are rotated. Some are not, but that’s okay. In the next challenge, you’ll have enough opportunities to practice rotation.
