Hey there, let's start with your superimposed lines - these are looking quite confident, particularly in the case of your straight lines. You've taken the time to line your pen up with the starting point which has minimised fraying to one end of the line. That said, your curved lines show signs of hesitation and you tended to try to bring your arm back into line with the guide line rather than letting it follow the original trajectory of your line which has reduced the confidence of your marks.

Next, your ghosted lines and planes are looking great. They're straight, confident, and quite accurate to boot. I did notice a small amount of arcing particularly in the longer lines. This is pretty normal and we can try to counteract this by arcing slightly in the opposite direction.

Your tables of ellipses are off to a good start. You've packed the ellipses in there nice and tightly and varied up the size and shape of them throughout. I did notice a little bit of wobbling in some of them and an overall sense of stiffness that might indicate you're either not executing these as confidently as you could be or that you're allowing other pivots of your arm to engage, in order to get more accurate ellipses. We recommend students prioritise confidence over accuracy as accuracy is something that will come with time and practice.

Next your ellipses in planes are looking great - they're hitting the four sides of the plane more often than they're not and you haven't sacrificed confidence to achieve this. I did notice one or two occasions where you drew through your ellipses more than 2-3 times which has resulted in a visually "heavy" appearance, so keep an eye on that.

Finally, you've done a pretty good job aligning your ellipses to the minor axis. Your smaller ellipses here again are looking a little less confident and the generally heavier line weight suggests to me that you're pressing harder on your pen for these. In terms of the alignment, you generally start off in the middle with worse alignment which slowly gets better as you go out. This might mean you need to rotate your paper to find a good angle of attack for these as I've noticed when I personally do this exercise, I can end up misaligned if I'm not approaching it from my best angle or if I've got my head tilted.

Onto your rough perspective now and what stands out to me is how straight and clean the lines are for the front planes of your boxes. I'm not sure if you used a ruler here - in the case that you did, this exercise is meant to be done entirely freehand besides the horizon line and frames. If you didn't, well take that as the ultimate compliment to your linework. The back planes are much less clean however, so make sure that you remember that the horizontals being parallel and verticals being perpendicular also apply to these planes. Finally, your estimation of perspective here is pretty good. Where it strays, it does so on boxes further from the vanishing point, which is completely normal.

You've done a good job keeping the gaps between your boxes consistent on your rotated boxes. It does get a little confused on the back planes of the left and right sides however, so remember that these boxes being tight up against one another gives you the best chance of estimating where the next box should go. You've managed a little bit of rotation across the exercise, with your inner layers possibly a bit too subtle in their rotation and the ones that follow tending to follow the vanishing points of the previous boxes, rather than having their vanishing point slide along the horizon line. Rotated boxes and organic perspective are designed to introduce students to new kinds of spatial problems they may not have otherwise considered and give them concepts they can work with in the 250 box challenge, so we only look for a completed attempt to the best of the student's abilities.

Finally, you've created some really cool looking compositions in your organic perspective exercise, with the variation in the sizes of your boxes, as well as careful overlapping conveying a good amount of depth in each scene. I noticed that you opted to use line weight to clarify some of these overlaps in your exercise and this is well done in some places but not so much in others. When you apply line weight, you should be doing it with the same level of confidence you would in the superimposed lines section. It's okay if you overshoot or end up with the line fraying off a little, because it's still adding a visual weight to that line, which looks much tidier than a wobbly one. I would suggest you keep practicing this in your box challenge as it's awesome free mileage, just make sure you only apply it to the silhouette.
