Hello aeshnabx!

Overall, you are off to a really nice start!

Lines

Your lines are overall pretty confident with smooth and continuous flow. There are some that waver/wobble, particularly on the ghosted lines, as you draw towards the targeted point. To note, confidence should take precedence and be prioritized before accuracy. It’s ok that the lines aren’t fully accurate, as it is imperative to first develop the shoulder muscle memory to draw out smooth, confident strokes. Essentially, a confident stroke that is slightly inaccurate is better than an accurate but wobbly line. So continue to ghost and execute every line with your shoulder.

Though it's a rather rare occurance, I'd still like to point out that on the 2nd page of the ghosted planes, some lines overshoot way beyond their end points. While yes, they go beyond their trajectory, they are confident lines, and that's more important at this stage.

Ellipses

Ellipses are off to a good start and are generally confident. There are a couple of exceptions, where a couple of ellipses wobble or turn sharply as you fit them in their allotted spaces. Just as with lines, focus first on confident smooth strokes. Then work on maintaining its roundedness, and then accuracy last. Ellipses in the funnel are generally aligned to the minor axis (just a couple snuck away, like the bottom ellipses of the top left funnel). Also, great job drawing through each ellipse appropriately (2-3 times).

Boxes

As you continue to go through your boxes, there are some nice confident lines. But there is still a fair share of hesitant lines. So remember to take your time to plan, ghost, and execute the line confidently with your shoulder for every line.

Also, some lines are repeated/corrected. No matter how tempting it is to correct an errant line, do not correct or repeat over it to correct it.

Plotted perspective

Not much to say here, looks good!

Rough perspective

You’ve done a pretty nice job maintaining horizontal lines are parallel to the horizon line, and vertical lines perpendicular to it. The convergence to the VP aren't too bad.

Rotating boxes

First off, congratulations on getting through this exercise! The boxes are generally rotating along the vertical and horizontal axes, so nice job with that. You are drawing through all of your boxes, which is great! The boxes could afford to be tighter in terms of how they are neighbored to each other.

Organic perspective

As the boxes get slightly smaller on the path, you’ve conveyed a sense that they move slightly away from the viewer. In terms of perspective, there are some sets of parallel lines that diverge away, making planes that are further away appear to get larger instead of slightly smaller. While not a big deal, a lot of the boxes have the same type of orientation. But no worries, you'll get plenty of practice and opportunity to experiment various orientations in the 250 box challenge!

With that congratulations on completing Lesson 1!
