Hello Kento, I hope you are well,

Starting with your lines.

You did quite a good job finishing those exercises. There aren't any major mistakes, just one minor. It is that In superimposed lines you fry both ends. It is normal to fry one end, but frying both, tells me that you don't prepare enough for each stroke. Remember to plan each stroke by positioning your pen on the start of your line, then confidently execute the stroke.

Your biggest problem with this section is that your lines wobble and aren't as straight as I would want them to be. Remember to be patient with ghosting and take as much time as needed for each line. Then when it feels right, confidently execute the line. Also keep in mind to use your shoulder with a locked wrist. You also arch your lines, you can try to arch your shoulder a little in the opposite direction to your arching. At first it may feel weird but after some practice it should make your lines straight.

I want to point out that you do a good thing focusing on confidence rather than accuracy. But in the end your lines aren't confident as pointed out earlier. We want to progress step by step and our 1st step is a smooth confident line that misses our mark a little.

Moving onto your ellipses.

Remember to draw through your ellipses 2-3 times. Doing so we gain experience with them faster. This also allows us to create a smoother shape of our ellipse.

You focus more on accuracy rather than smooth and confident ellipses. Keep in mind that what we want from this section is a habit of drawing through our ellipses and making them as smooth as we can. We do it by ghosting our ellipses and executing them with confidence.

In ghosted planes keep in mind that center of a plane isnt a center of our ellipse that we want to draw in. Ellipse has to be symmetrical and also has to keep the same form regardless where they are. Also few of your ellipses aren't smooth.

On funnels, you don't align ellipses to the minor axis. Remember that our ellipses should be cut by the center line in two symmetrical halves if that means you need to ignore the initial curves. In tables of ellipses try to make your ellipses within the bounds of tables and don't make them overlap each other, this happens quite rarely but I still want to point it out for the future.

Lastly your boxes.

This section came out good. Your linework got a little better, but another problem appeared. Repeating lines is a bad habit most students do in this early lesson. Don't repeat your lines, even if you made a bad line, leave it and treat it as if it was the correct one. We don't want to correct our lines as it forms bad habits and teaches us that we don't have to commit to our lines. Leave your bad line there to be seen. Next time you try to make a line, don't repeat the same mistake you did the previous time.

You did quite a good job in rotated boxes, most students struggle in these exercises and they are supposed to as it is the hardest part of this lesson. That said, sometimes you are actually not rotating them, but rather skewing and translating over. When we rotate a box we also move its vanishing point, use this gif to understand how the rotation is correlated with the motion of the vanishing points.

In your organic perspective you arent varying the sizes of boxes enough. As it stands now your boxes are very similar in sizes. Additionally remember to overlap your boxes, don't avoid it. We want them to be overlapped and varied in size to make a strong feel of perspective.

Summary

There weren't any major mistakes, just a few minor ones. But your weakest point is your line making skill. Remember to always be confident with your lines and ellipses.

I want you to make 2 pages of ellipses in planes as a redo, as I believe improving this skill will help you greatly in future.

If you have any question feel free to ask,
