Good job for completing your homework! : D

I'll take care of reviewing it, I'll try to be concise with the details.

Let's start

Arrows:

  • Your arrows look well drawn, both in the fluidity of the lines and the sense of depth.

    I like that you have no problem folding them in on themselves.

Organic shapes / Ellipses and contour curves:

  • The overall shape of your "sausages" looks good, nothing out of the simple.

  • The ellipses are well aligned, and you are also trying to change their degree (thickness) properly; I know the latter will improve with time.

  • The contour curves don't look bad, either.

  • Still, you seem to be focusing a lot on how many ellipses and contour curves you draw.

The more of these you draw, the more likely you are to get tired and the quality of them decreases.

Just draw a couple, but well planned. Calculate the correct curvature that each one should have, and avoid making them look flat.

Texture Study:

  • The textures themselves look good. But the transition from dark to light could be extended a bit more.

As in the last section of this image: https://d15v304a6xpq4b.cloudfront.net/lesson_images/7d1f3467.jpg

You'll notice that the dark section will have a denser, more embracing shadow pattern, which blends into the transition's starting bar.

Meanwhile, the light part will have smaller, less embracing shadows that barely touch each other.

Dissections:

  • Your textures roll nicely into the sausage shape.

-It is also very helpful if you are modifying the silhouette of your dissections.

This way, you will get a better impact on the description of your shapes.

  • In several textures you are focusing too much on outlining the shapes; when your focus should always be on the shadows cast.

Think more about identifying such shadows, and just take care of drawing those, nothing else.

Intersection of shapes:

  • All the shapes look like they belong to the same scene because of their similar size and foreshortening, all good on that part.

  • I see that you worked a bit with the intersections, if you still don't understand them don't worry; later we will see them again in more detail.

  • Your mastery in drawing each shape is also very good, there are not many details I can mention here.

Organic intersections:

  • The shapes look good resting on top of each other, that's great.

Still, you can always improve that effect; I recommend you to see the following image to clarify the subject:

To get a better sense of solidity and stability try to imagine that you are stacking water balloons.

  • I like that you've captured how the shadows cast on the shapes are cast.

I know you will progress even more with practice.

Conclusion:

It is seen that you have understood the general themes of this lesson, so I will correct your lesson as Complete.

Best of luck in what follows, always with effort!
