Hi Nobody, good job getting done with lesson one! I will handle your critique. I can already tell you that I think that overall you did a great job here, nevertheless I will still try to give my opinion on each exercise and tell you where I think you did well and where I feel there may be eventually room for improvement.

Superimposed lines

From the beginning you show that you already have a pretty good control over your lines. I see virtually no wobbling in your straight lines, and fraying on only one end as it should. Similarly, your curved lines look very confident and each repeated follows very closely the established curve.

Ghosted lines

Here again, aided by the ghosting method, your lines look very confident, almost perfectly straight in some cases. They also follow very closely the direction established by you fixed points of choice with little deviation or arching, and very little overshooting or undershooting too.

Ghosted planes

Much of the same I said above applies here as well. You experimented with a fair amount of different shapes of planes, which is good and will come in handy for later exercises where perspective will become a factor to consider. A small critique I will make is that in one of the planes on the left in the first page, one of the sides is made of disjointed lines. If this was caused by an attempt to correct your trajectory, remember that here we will always prioritize confidence over accuracy, so if you ever notice a mistake in one of your marks, try to resist the urge to correct yourself midway, because the result will probably end up looking less confident. Instead, try to work with and around your mistakes on the paper.

Tables of ellipses

Your ellipses look very smooth and confident. You experimented with a fair range of eccentricity, from almost circular to relatively elongated. The ellipses look more often than not fairly symmetrical, the more elongated ones more than the more circular ones as it usually is the case. You also correctly drew two times through each ellipse. Also, good job with the efficient use of the space of each table, they all look filled with little room for addition.

Ellipses in planes

The planes were a little more challenging as a boundary for your ellipses, but you were more than up to the task. Your ellipses remained confident and for the most part symmetrical, even in the trickier, more deformed planes. Sometimes you ended up overshooting the plane by a bit, but it's not much, and you correctly prioritized confidence over better accuracy.

Funnels

In the first funnel in the top let corner you seem to struggle a bit with aligning your ellipses with the axis of the funnel, but you quickly corrected your shot in the following ones. You also followed the additional step of making you ellipses less eccentric the more you get further from the center, which is good since it will come in handy later in the course. Before moving to the next sections, I will point out that it looks like you free handed your funnels, or at least some of them. While the result looks generally fine, since in this exercise we are trying to use rigid guidelines to make our ellipses as symmetrical as we can by aligning their minor axis with the axis of the funnels, it would be a good idea to trace round objects to make your funnels in the future, when you will revisit this exercise in your warmups, in order to minimize the asymmetry.

Plotted perspective

Not much to say here, you have applied correctly the steps for using two point perspective. My only nitpicks here are that some of your verticals are a bit slanted (one way to correct a bit this when you are using a graduated ruler only is to align the scale marks to the sides of your panel) and that some of your hatching lines look a bit wobbly. Remember that a hatching line is a line like any other: it should be traced smoothly and confidently using the ghosting method.

Rough perspective

Your lines look again confident like they did before. You apply correctly the rules of one point perspective, as your extension lines show. The directionality of each individual side of the lateral faces is correct, with the boxes broadly leaning away from the viewer and towards the horizon. I see that you have also applied line weight to some of your boxes, which is good. In some of the boxes occasionally a stray side ends up diverging instead of converging, and you seem to have a bit of a tendency of placing the sides of opposite faces in such a way that they end up converging in two fairly distanced distinct points. While these are mistakes, I wouldn't worry too much about them since this is your first approach in this course to freehand perspective and you will have plenty of time to practice during the 250 boxes challenge.

Rotated boxes

These last two exercises are notoriously more complex than the rest of the lesson, but you did a nice work. The boxes are well rotated and you did a fairly good job at filling the "corners" between the arms of the initial cross. For the hatching lines, my previous critique applies even more here, where the lines look more like scribbles (which should always be avoided here) than confident lines that communicate depth.

Organic perspective

Very nice job here. The boxes follow smoothly the path of your curve and get bigger approaching the viewer. Compared to the rough perspective, you seem to be more comfortable when you have to just eyeball the perspective deformation of your boxes, resulting in quite believable shapes in 3d space. This shows that you may have already a good deal of perspective intuition, which is a skill that will come in very handy in the 250 boxes challenge as a tool for double checking and simplifying the task. Good job again on applying line weight consistently and only on the outside of the boxes.

Keeping in mind the criticism and suggestions I gave you above, I feel that overall you did a very fine job with your first lesson and I can confidently say that your are well equipped to begin to tackle the 250 boxes challenge. Good luck and stay motivated!

EDIT: I didn't notice that this submission had already a critique. Still, I hope that my thoughts will prove useful to you.
