Hello!

Congratulations on getting through your first lesson!

I'll be handling your critique;

Lines: The one thing that I'd like you to keep in mind with your lines is that the lines should always first and foremost be smooth and straight. In your lines I see mostly wobbling more so than curving. So remember to take your time to apply the ghosting method before drawing the line confidently, using your shoulder to execute the line in one one smooth stroke. The slight wobbling also seems to indicate that you have slowed down, so at the beginning especially it is advised to draw your lines faster. In the superimposed lines exercise keep in mind that the line should not fray on both sides: remember to start your lines from the starting dot. Also, your superimposed lines are all straight lines. In the future I'd recommend adding curved lines into this exercise when doing warm-ups as the ability to go over curving lines again to add line-weight becomes really useful in the later lessons. I don't see any cases of you redrawing your lines, which is a good thing! In the future I'd like you to pay extra care to your line quality and only after getting that down worrying about accuracy.

Ellipses: In the ellipses I see some wobbling as well. Just as with lines the goal is to have your lines be smooth and confident. Another thing to keep in mind is that they should be evenly shaped. You can take a look at this to see more concrete examples: https://d15v304a6xpq4b.cloudfront.net/lesson_images/a76a8906.jpg .I also see some hook type of things on the top of your ellipses. Try to get rid of those. So with ellipses remember to draw confidently, using the ghosting method until you feel ready to execute the mark. When executing your lines draw with your shoulder without worrying about accuracy. Drawing ellipses with a greater speed might also help you. You have remembered to draw through your ellipses. Good job on that!

Now I'm going to point out things about your accuracy. Accuracy in ellipses is probably hardest thing in this lesson, which is why these things are completely normal mistakes to make. I am saying this for you to have as a future reference, so please do not worry about accuracy right now, Ellipses should be kept within bounds of each other or the borders in the exercise tables of ellipses. Also, I'd recommend having more variety in the angles of your ellipses as shown here: https://d15v304a6xpq4b.cloudfront.net/lesson_images/f4181ea2.jpg . Your ellipses seem to be mostly upright. In the ellipses in planes the ellipse should ideally touch all four sides of the planes. In the funnels the minor axis should cut the ellipses in two symmetrical halves. You have succeeded in this in some cases. Great job!

Boxes: Plotted perspective: good job! Nothing to mention there. Rough perspective looks good as well. The main thing in that to keep in mind is to have the height lines perpendicular to the horizon line and the width lines parallel to the horizon line. You have succeeded in this in most of the cases. Well done! In the rotated boxes the boxes farther back should be rotating little more. Organic perspective exercise looks also good. One thing I will mention for your box challenge is that remember to keep the initial "Y's" angles should all be greater than 90 degrees to avoid distortion as seen here: https://d15v304a6xpq4b.cloudfront.net/lesson_images/7e325b33.jpg .

Overall you have done all your exercises well! Good job! Before I mark your lesson complete I'd like you to do a page of Ellipses in Planes where I want you to put extra care into making confident marks. Despite the nature of the exercise I don't want you to focus on accuracy in your ellipses rather try to aim for an evenly shaped ellipses that don't have wobbling in their lines. Also try to draw each line carefully ad well without wobbling. The other things I mentioned you can address in your warm-ups.
