Lines

Pretty confident and smooth overall, good job! You do have fraying on both ends at times, so careful with it, when starting a line, you should carefully place your pen on the start of each line, so only a maximum of 1 end can fray. Plan each stroke you make carefully. Some of your lines overshoot quite a bit, which is completely normal, but be sure you're ghosting enough on each line, take your time.

Ellipses

Ellipses are p good as well, though they get a tiny bit of wobble at times. Don't forget to prioritize confidence over accuracy on them, just like with lines. On funnels, you've mostly done it, but don't forget that the minor axis has to cut the ellipses in 2 identical halves, if you have to ignore the curves to make them symetricall, ignore them.

Boxes

P good job overall, though a few things.

On rough perspective, you seem to have trouble keeping height lines perpendicular to the horizon line, and width lines parallel to it. I know it's hard, but be sure you keep it in mind while attempting the exercise.

Rotated boxes is hard, and you did a p good attempt, but there are a few instances where you don't rotate the boxes, givethis.) a look to make sure you're aware of it.

There are also a few instances where I think you aren't plotting your lines, before starting any line, you should first draw the starting and ending dot of it, don't forget about it, as it's super important for applying the ghosting method.

In general, you seem to be rushing in the last exercise too, don't forget to take your time, if you need a break, take it, you can complete exercises in more than one sitting too if you feel you're getting impatient.
