Hello LAUTARO

Congratulations on finishing Lesson 2.

Arrows:

The lines of the arrows could be more confident. It seems like you rushed a little bit in the parts where you connect two lines, or where you draw the arrowheads, resulting in wobbly and inaccurate lines. Also, the line weight should be done with 1 line, so the line weight is not overdone.

I like how you compressed your arrows. They get bigger, and the distance increase in each fold as they go towards the viewer, and they get narrower and smaller as they go away from the viewer.

Organic Forms:

Your sausage shape is a little different than the one shown in the homework material. They should be 2 identical balls connected by a tube of consistent width. You can check the shape from the lesson materials here. This will come into play in future lessons, especially as we use these as one of the basic forms of organic construction. So, I would recommend you draw the exact shape shown in the lessons rather than the straight ones you drew in your homework. Also drawing some smaller ones might give you more space to work with, and this way, you can practice with more shapes.

The degrees of the ellipses should change. According to the lesson, as you pick a different position along the length of that sausage form, the orientation of that cross-sectional slice is going to be a little bit different relative to your viewing angle, resulting in a slightly different degree. Most of the degrees of the ellipses in your homework don't change much. So when you do this part as your warm-up, be mindful of the degrees.

Ellipses and the contours are aligned well with the minor axis. Also, it is good that the contours wrap around the round shape, as it is a very important part of the lesson. But in one shape, the contours are outside of the shape, which doesn't give the impression of roundness.

Texture:

On the texture part, the main thing is to draw the cast shadows and not the lines. In Texture Analysis, you made a good job drawing the cast shadows, and the transition on the gradient is well done. But there should be three texture analyses, whereas you have only two.

In the Dissections, you have a small number of sausage forms, and it seems like you draw the outlines of the shapes instead of the cast shadows. Also, textures didn't wrap around the round shape.

According to Uncomfortable, since this part is only an introduction to the topic, you don't have to do it again. You can practice them as your warm-ups. As you finish more lessons, your understanding of texture will improve, and you will get better results.

Form Intersections:

In this part, the lines, just like in the box challenge, should be drawn confidently and not be repeated. All the lines should be ghosted before drawing it. So try to plan your shapes and your lines before drawing them, ghost them as much as you need, and then draw them at once, confidently. This increases the time you spend drawing each shape, and it takes a longer time, especially since we have to draw several shapes in this part. But taking your time drawing them will help you produce more clean and confident shapes.

In some of the shapes, the foreshortening is too deep. The main objective of this exercise is to make all the forms appear that they share the same scene. To achieve this, the forms need to have consistent foreshortening. It's easier to achieve this if you keep your forms equilateral and focus on only shallow foreshortening.

The intersections should be drawn with the same pen you used for the shape, a black fine liner. I believe it is mentioned in the video of this lesson. Using a different color of pen brokes the illusion of the solid form. The intersections explain to the observer how the shapes are related to each other. If you draw them with a different color, they will appear as lines, instead of shared edges of two intersected shapes, which will kill the illusion of one big solid object.

According to the lesson, you can add line weight to help develop a hierarchy to your drawing, but line weight should only be added to local sections of existing lines to emphasize them and clarify overlaps. Don't go applying line weight to the entirety of a line, ESPECIALLY not to your ellipses. You can check the whole lesson from here.

Organic Intersections:

Your shapes in the Organic Intersections look nice. Some of your shadows look like they are sticking to the form. The shadows have to follow the form of the object they're being cast on, not the form of the object that casts it. Also, most of your lines are drawn more than once, especially the contours. In every exercise you do in these lessons, you should draw confidently, from your shoulder, and at once. You can't draw the line again or go over it when the original line doesn't come out the way you want it to be. This will only create a messy look.

All in all, I see you understand a lot of the basics of this lesson. But I feel like you rushed through some of the exercises. In every line you make, you should plan it out first, ghost it, and then draw it at once, confidently. Don't try to fix your mistakes. We are bound to make mistakes as we proceed, and that is okay.

I think you can go ahead and start Lesson 3. But don't forget to incorporate those exercises into your warm-ups. Also, when you do your warm-ups, it might be a good idea to check the relevant lesson material to see if you are missing any important points.
