Thanks for your critique, especially pointing out my mistake in dissections, because it seems really flat sometimes. I've almost completed lesson 3, so I'll move onto 25 texture challenge.

Have a nice day!

Arrow exercise

In this exercise, I can see that your lines are drawn with confidence and I can easily notice what you mean. However, I would be more aware of adding line weight, because sometimes you just draw another line instead of adding weight to one that already exists.

Organic Forms with Contour lines

In this exercise (especially contour curves) your lines turned out really wobbly. I think you forget to apply the ghosting method. I also don't want you to draw a lot of small organic forms. Make them bigger and more solid. I also have to point out that your curves are too shallow.

Contour elipses are a bit better, but sometimes your elipses are not rotated in the right direction, which makes your organic forms flat and hard to understand. However, good for you, lines are drawn with more confidence.

Texture Analysis

This exercise is great, I can notice that you understand the texture you were drawing. But you forgot to leave a white bar at the end of the transition part. Don't worry about that, it's not such a big deal.

Dissection exercise

This exercise is good, I can easily understand the message. I didn't spot any mistakes.

Form Intersections

As this exercise is meant to be extremely difficult, you've done a great job, especially on the box intersections. Thanks to you, now I know how it supposed to look like.

Organic Intersections

Here you repeated the same mistake that I've made on contour curves. Your curves are too shallow. Maybe you can look at them as halved elipses. Also, remember that what you constructed is an illusion of 3D world. Look at your page as a window. You're looking for a new, tangible reality.

Also, be more patient with filling cast shadows in black, because there are some unfilled spots here and there.

In the beginning, I thought you were repeating the same boxes over and over again. But later I had broken this scheme, which I really appreciate.

One thing that I want to mention is line weight. At boxes 90-123 and 191-234 you added line weight to the plane that is facing the viewer, which is incorrect. As we use x-ray vision, you should add line weight to edges that you would be able to see in 3-d space.

As in boxes 139, 140 you sometimes don’t know in which direction you should extend your lines. Think you it where your lines converge, where they’ll meet. I think in 140 box you should add hatching at the bottom plane and it would solve the problem.

Those are the only little mistakes that I’ve noticed. You’ve done great work and progressed through this challenge.

At first, you missed that in 3 point perspective lines should always converge towards the vanishing point because yours are extremely straight. Try to estimate where your vanishing point is (even if it is way beyond the page) and then draw them according to your observations.

Secondly, You approached cross-hatching instead of hatching lines. They also look like you were hurrying up. As mentioned in draw-a-box, if you don’t want to draw it carefully, don’t do that. However, I encourage you to be a little bit more patient, and draw them, as they should be drawn.

In some boxes, you extend your line in the wrong direction. Remember that lines converge towards the vanishing point.

At first, your lines are wobbly. I think the problem is that you didn’t draw from your shoulder. Also, remember that we prioritize confidence and smoothness over accuracy. But you progressed through exercises, so don’t need to repeat. Also, some of your lines arch, when it happens try to rotate them in opposite direction.

On the ellipses section, some of them resemble more eggs than ellipses. I think it could be easier if I would have started from smaller ones.

In plotted perspective exercise, you could have drawn more boxes. Of course, it’s not a problem, but you would get more practice out of it.

I was impressed by your rotated boxes – you show a lot of a box and how it rotates in 3d space.

You’ve done a great job and progress through lessons.

Good luck on 250 boxes challenge :)

Line section is pretty good, but in ghosting lines exercise some lines arch at the beginning and the end. When it happends, try to draw a line rotated in opposite direction.

Your elipses are great, they are smooth and drawn confidently. I only wonder why you made another planes for elipses because you could use ones from ghosted planes exercise.

On rotated boxes you should fill corners with boxes.

You’ve done good job and I wish you lack on 250 boxes challenge!
