Hi, I'm Znorb, and I'm going to do your lesson 2 critique:

Arrows

I see you are doing a great job on the size of the arrows, the size of the arrows should become smaller because they're getting farther away

There are some things you can improve on, for example, some arrows have edges that don't overlap (https://d15v304a6xpq4b.cloudfront.net/lesson_images/1e23d6b7.jpg)

Organic forms

The main thing I can see is that some of the organic sausages you draw are elongated and thin. Don't try to make the shape too long. Try to make the sausage shape more simple, like if the shape was 2 spheres of similar size connected by a tube with a consistent width:

Textures

When doing the textures, try to not make chicken scratching, focus more on the shape of the cast shadow and then fill it. In the texture analysis video demonstration shows a way to do this

Textures in organic forms

Something I could say about the textures is that some of the textures should break the silhouette. When drawing the texture, don't be afraid of breaking the silhouette, because it helps you understanding how the form of the texture works and how it wraps around the sausage. For example, in the strawberry texture, you could've put seeds that break the silhouette of the shape, and in the pangolin texture, the shapes of the pangolin should break the silhouette

Form intersections

I see you are doing great with the boxes intersection page. In the other pages you should've added more shaped, like in the box page.

Other thing I see is that some of the boxes have a more distorted perspective than others, remember that the boxes should have a very similar distortion, so is recommended to make the boxes with less dramatic distortion (https://cdn.discordapp.com/attachments/503600256374669324/1092172418488995851/Untitled.jpg?ex=66407314&is=663f2194&hm=c5c8d3d31f93eee78f4065b27e515219d85b487055b79160486c771c908c75ee&) . Besides that, I see you did a great job on the form intersections page

Organic intersections

I can see the same mistake on the organic intersections about the form. Try to not overcomplicate the shapes of the saugages, try to stick on simple sausages (https://d15v304a6xpq4b.cloudfront.net/lesson_images/4213ce18.jpg)

I can see that some of the shapes aren't laying, when doing the shapes, try to lay all the sausages in perpendicular, keep in mind that the sausages are 3d and they have volume (https://d15v304a6xpq4b.cloudfront.net/lesson_images/5de674b5.jpg)

And again, try to not do chicken scratching when doing the shapes of the cast shadows

After all of this, I can see that you are getting better at drawing, and if you continue practicing the exercises of the lesson 2 and lesson 1, you will become better and you will see the mistakes of your previous drawings.

I will mark this lesson as completed, keep practicing the concepts of the other lessons having in mind the corrections, good luck with the lesson 3!!

You should check the texture challenge too, it will help you a lot with the texturing.
