Hello Ran, thank you helping the community by giving critiques! I'll be looking over your submission.

Starting with your arrows, they flow through the scene pretty fluidly. Your lines are both confident and accurate, and you did a pretty good job with compressing the further end of your arrows.

Moving onto your sausages, they look pretty confident as well. Even though you were trying your best to stick to simple sausages, you aren't fully there yet. Remember, your sausages should always look like two identical spheres connected by a tube of consistent width. You did a good job with playing with the degrees of your ellipses to create a dynamic image. You generally did a pretty clean job with your ellipses as well. they stay within their bounds and are usually aligned to the axis line.

Onto the texture analysis exercise, I feel like you weren't paying enough attention to your reference images and therefore, instead of looking like they were actual cast shadows drawn purposefully, some of your shadows kind of look like random scribbles. Here is a handy guide to help you with getting used to drawing cast shadows instead of lines.

The dissections exercise looks pretty good however. Your textures wrap around the texture nicely and you generally did a pretty good job with breaking the silhouette.

In the form intersections exercise, the main goal is to create an image where every form can sit together without breaking the scene and you managed to do that by creating forms that have similar foreshortening (except for a couple of boxes). Your lines look pretty clean as well. And even though you weren't required to show the actual intersections for this lesson, you generally did a pretty good job. But I just want to point out, you forgot to draw through one of your boxes in the first page, this isn't a big deal but I wanted to put it out there.

Just like the form intersections, your organic intersections looks pretty solid as well. You managed pile a lot of forms on top of each other and still make them look stable. Your use of line weight and shadows help make the scene less confusing as well.

Overall, you did a pretty good job! I'll mark this lesson as complete so now you're officially done with the basics, congrats!

One thing though, it would probably be beneficial to try doing more texture studies in the future, you don't need to complete the entire 25 Textures Challenge if you don't want to, just do a couple of textures and pay close attention to your reference image.

If you have any questions don't hesitate to ask me here or tag me on the discord channel. Have a great day!
