Hey there!

So let's start off with you lines section.

Your superimposed lines have some fraying. It is expected however, and you will find that with extra mileage and practice you accuracy will improve and that will result in less fraying.

In your ghosted lines and planes exercises your lines are looking smooth and confident. You do have some arcing occuring which shows that you are not fully comfortable using you shoulder and relying on your wrist/elbow a bit too much.

Now onto your ellipses.

You are off to a decent start but I notice a few things worth mentioning in your table of ellipses. Don't be afraid to experiment with more shapes and sizes, while not all the same you did play it a bit safe with your choices here. You can try drawing larger, smaller, thin, wide, angled ellipses as well, experimentation will help you build up a strong foundation of understanding what to use and when it's applicable.

With that being said you may also be drawing your ellipses a bit too hastily as they're quite loose in some places. Just take your time and ghost before making any mark.

In the funnels exercise you did a good job aligning your ellipses to the central axis, just remember that as we are going away from the center our ellipses' angle (width) must increase.

Now onto your boxes.

Good job on your plotted perspective.

In the rough perspective exercise your correction lines end up in the general area of the vanishing point which is good to see and shows you have understanding of perspective.

You did amazing job on your rotated boxes.

As for the organic perspective exercise you have shown that you understand the further away a box is from the viewer the smaller it gets which is great. Your boxes themselves could definitely be constructed better but this is a good start and you will have to do the 250 box challenge next so hopefully this will help your understanding in box construction.

Overall you've shown that you understand the core concepts being taught in this lesson so I'll be marking your submission as complete and moving you on to the 250 box challenge where you'll gain a better understanding of working in 3D space as well as working with multiple vanishing points. I do want to remind you that you still have to do those exercises for warmups.

Good work so far and good luck in the 250 box challenge.
