Lines

Starting with your superimposed lines, you're doing a good job here - your lines are smooth, confident, and you've taken the time to line your pen up with the starting point which has minimised fraying to only one end of the line. Your ghosted lines are similarly confident but you do seem to be restricting yourself to fairly short lines, so make sure you mix it up so you can really engage that shoulder. Your ghosted planes are similarly well done, though watch out for the little bit of arcing that's shown up here.

Ellipses

Your tables of ellipses are looking fantastic. The ellipses themselves are smooth and well-drawn and you've managed to pack them in there nice and tight. There's also a good amount of variation in the shapes and sizes of your ellipses - overall a very well executed exercise. This trend continues to your ellipses in planes and whilst they're popping out of the plane here and there, you haven't sacrificed confidence for accuracy. Finally, your ellipses are pretty well aligned in your funnels, there's very minor skewing here and there but honestly that's more of a nitpick than anything else.

Boxes

Your rough perspective is looking pretty good! I had to double check you'd extended your lines the right way because you've managed to land them within a pretty reasonable degree of the vanishing point. That said, do watch out for your line confidence here - your lines got significantly more wobbly here and you reinforced some of them with a more cautious stroke, which has resulted in the linework getting a bit untidy.

Similarly to the previous exercise, your linework suffered on the rotated boxes but overall you did a good job of the exercise - you've kept the gaps between your boxes tight and consistent on the front and rear planes, which has enabled you to rotate your boxes quite well. If I had to pick on one thing, it would be that the outer boxes could probably be pushed slightly further in terms of rotation.

Finally, your organic perspective is showing a lot of promise - your boxes look pretty good and you're starting to get the sense of scale building with the variation in size - if you wanted to push this further, you could look into overlapping your boxes a little more as well as drawing a few more of them in each composition.

Please consider this lesson marked as complete once again. I noticed you had the lesson 6 badge and I'm unsure if you're going through all the lessons again - if that's the case, then I'd suggest doing 150 boxes for the box challenge rather than the full 250 before you move onto lesson 2.
