Starting with your superimposed lines, these are looking fairly confident and well-executed. You've taken the time to line your pen up with the starting point, which has reduced fraying to only one end of the line. I noticed your curved lines were slightly less confident, so make sure you work on getting these confident in your warm-ups.

Next your ghosted lines and planes are looking straight and confident for the most part. I can't tell whether it's the photo quality or whether there's a little bit of microwobbling along the lengths, possibly indicative of pressing down too hard. There is also a small amount of arcing present but otherwise these look pretty confident and accurate.

Onto your tables of ellipses which are looking confident. Great to see a wide variety of different shapes and sizes of ellipses. It does seem like you're having a little trouble controlling where they land, so make sure you're taking the time to ghost these out till the motion feels fairly natural. Finally, it's nice to see you've packed most of the sections with lots of ellipses all tight up against one another, though less so hitting the borders of the section.

You've done a good job hitting the four sides of the plane in your ellipses in planes exercise. You haven't sacrificed confidence for accuracy here and whilst there's still a few instances where they're not hitting all four sides, this will level of accuracy will come with time and practice.

Finally, the ellipses in your funnels are overall quite well aligned to the minor axis. There's a couple of instances where they skew off a little but they tend to be towards the outer ends of your funnels which is a pretty common mistake as there's less guideline there to keep your ellipses straight. I did notice that you drew through your ellipses more than 2-3 times here, so make sure you keep that under control. Additionally, the smaller ellipses were quite wobbly - this is pretty normal, it's quite difficult to draw smaller ellipses from the shoulder as it requires finer control over the muscle than opening out to draw a larger one, again, this is just a matter of practice and being conscious not to let any elbow or wrist movements sneak in there to muddy up your muscle memory.

Next up, your rough perspective is looking really nice. You've done a good job in most cases of keeping your horizontals parallel and verticals perpendicular to the horizon line. Additionally to this, you maintained most of your line confidence and your estimation of perspective is about where we expect it to be, with the boxes furthest from the vanishing point being the most inaccurate.

Your rotated boxes are off to a good start. You've kept the gaps tight and consistent for the most part, which gives you the best chance of estimating the location and rotation of the next box - it does get a little looser towards the far edges of the exercise, which causes your boxes not to rotate perhaps as much as they could have. Overall, you've got a fair amount of rotating happening and we don't expect students to be able to nail this (or the organic perspective) exercise at this stage.

Finally, your organic perspective compositions are looking really good. You've done a subtle but effective increase in the size of your boxes which conveys a good sense of 3D in each of the scenes. You've also overlapped your boxes nicely which has contributed to this illusion. Your line confidence here is pretty good and I'm glad to see that you're not automatically correcting your mistakes as we often see. I did notice you seem to be pressing harder on the shorter lines, which might indicate you're not fully engaging the shoulder, or you're moving the pen a little more slowly on these. The boxes themselves are showing some signs of divergence, which is perfectly normal at this stage and is one of the reasons we assign the 250 box challenge to students.
