Hello and welcome to drawabox!

With Imgur is everything fine – all pages of your submission are there in one album and the exercises are in sequential order. But I would like to mention that due to some scanning setting (or something like this) your lines in some cases look ‘wavy’ (even those that are drawn with ruler). Probably it would be better if you chose some other settings for your scan that would show more close copy of your original drawing and would not ‘deform’ your lines.

Ok, now critique.

Lines

Superimposed lines are good. Lines are smooth, consistent, and properly lined up at the start. However, your lines are 'fraying' on the end, but in this stage, it is entirely normal. It will reduce with practice and time.

Ghosted lines/planes look quite confident, too. However, I notice that your lines in few cases arc as they approach the end point. It is fine for it to stop short of, overshoot, or miss the end point, because the goal here is – first confidence, then accuracy.

Ellipses

Tables of ellipses looks quite good. The good thing - they in the most cases are drawn around the ellipses 2 to 3 times. The orientation of ellipses (the angle at which it is positioned) is also consistent within the same section – that is good. Some ellipses are a little stiff but some of them are round and confident. Goal here is for them to be confident, and circular, first and foremost. Of course, it would be nice if their rotations were tight, and they themselves properly fit within their frames, but not at the cost of it.

The same situation is also with ellipses in planes – needs more confidence over accuracy.

Funnels. Your ellipses are good. The minor axis cuts each ellipse into two equal, symmetrical halves. And bonus point - the degree of your ellipses increases as you move outwards from the centre.

Boxes

Plotted Perspective. Exercise looks good (even though a few ‘invisible’ lines are missing).

Rough Perspective. Here I see good attempt - 2 sets of lines are mostly parallel/perpendicular to the horizon, and 1 set try to converge towards it. Even though you have mistaken in your estimations, the boxes still are likely to look close to correct. And for this stage it is enough, if not this - I noticed that some lines that converges to the horizon in your boxes are much longer than needed for particular box segment . If this ‘longer’ line of box is the line that determines the length of your box then stick to it and plan next points according to the exercise. If this is not the case, then plan more accurate corners of boxes. It is entirely normal adjust your firstly planed points while you got the one that satisfies you and only then to draw a confident line between the planed points as it was in ghosted lines.

Rotated Boxes. Good work on this exercise - gaps between boxes are quite narrow and your boxes are rotating (may be a little quickly, and probably that’s why the exercise is missing 4 boxes (the corner ones)). However, I noticed that you started to correct your lines and, in some boxes, made them bold. Try to avoid repainting or correcting your ‘confident’ line. Each line should be drawn only once, regardless of how it turns out. Just let it be and move on.

Organic Perspective. Well done. You have constructed boxes along the swoopy line and making the boxes that are far away smaller and those who are closer - larger. I noticed that you in the organic perspective exercise also considered that ‘parallel’ lines have their vanishing points and you planed points for your lines. That is great.

Overall, I see your improvement during this lesson and that is good. And in my opinion, you have submitted your homework in the best way of your current ability, so, I let you go through to the next lesson.
