Lines and ellipses are p confident and good overall. You do have some wobbly lines, both on ellipses and lines, but they are the minority. Be sure you prioritize always confidence over accuracy though. A confident line will always be better than a wobbly one.

On boxes you've done mainly a good job, though it seems you struggle a bit to keep height lines and width lines, perpendicular and parallel to the horizon line respectively. Be sure you are aiming for this, I know it's hard.

You're also repeating some lines. No matter how off a line is, don't repeat it. Keep going as if it were correct.

On organic perspectiveI recommend trying more overlaps. You can clarify after the overlaps by adding a confident, drawn with the shoulder superimposed line on the part of the silhouette of the boxes that overlap. Perspective on them has issues but you'll work on it on the box challenge, so don't worry about it!

Hey. Good job finishing the first lesson.

Here's my opinion on your work.

Lines

Your superimposed lines show a good confident stroke, they arch a bit in some examples, but no wobbling at all. The lines do frail at both ends, though, showing that you didn't take the time to place your pen correctly in the starting point before starting the line.

Your ghosted lines are overall good, although they have some slight wobbling, as it seems you were forcing yourself to hit both dots. straight, confident lines drawn from the shoulder is what you should be working on this exercise.

The planes are also good. You seem to draw over some lines in a few of them. Resist the temptation to do so. It doesn't seem you put the dots before drawing the middle lines, which is something you should be doing in this exercise.

Ellipses

Your table of ellipses are nice, showing mostly confident lines, but, in some occasions, they are a bit wobbly, specially on rounder ones. It seems you try to fit them in the space between their neighbours sacrificing they're roundness along the way. Again, have confidence in your ghosting method and commit to your lines, not trying to correct them along the way. Although this also is present on your ellipses in planes, it's in less number, which is nice to see.

Rough Perspective

In this exercise you seem to have done the front plane with a ruler, when you should have free-handed it. Despite this, your perspective lines are mostly converging correctly and, although some of your lines show some wobbling in this exercise, over all you did a good job.

Rotated boxes

In this exercise you start with some interesting rotation along the centre row and column, but you should and pushed the rotation further as you go to the corners.

Organic Perspective

Here you show a good sense of drawing the flow from farther away boxes to the closer ones. In occasions like this don't be afraid of overlapping the boxes and playing with the line weight in order to show wich box is in the front and which is in the back. On a few of them the perspective lines are not converging correctly, but overall you did an interesting work here.

i dont know if you use this or if its even you but if you see this you know who i am and im worried about you. if you want to reach out heres my email gokey.joshua@yahoo.com
