Congratulations on finishing your homework for this lesson! It must have taken you a while as there were quite a few animals.

There are many things that can be improved, and that's what I will focus on during the revision:

Organic Intersections: On both pages the sausages look a bit stiff, and the contour lines don't help as they look too flat.

It looks like you're rushing to draw them. If so, start taking more time to do it to get better results.

I drew corrections on these to explain some more technical things. The thickness of your sausages should be consistent and, each sausage should appear to curl over the ones holding it. Check out this image: https://imgur.com/qLHExue

Animals:

On the owl you worked too little on the face, it looks as if its eyes and beak are floating above it. This is why you should be careful to draw the facial planes, which will give us a better idea of the position of each feature.

I really liked the idea of drawing two animals on top of each other, it's a great way to practice how the shapes interact. Although I admit that the excessive amount of contour lines dulled the drawing a bit.

They gave too much stiffness or artificiality.

You can notice this in your ostrich drawing as well.

Finally I'll talk about what seems to be too little planning in your lines. There are drawings like the tiger on the yellow sheet where it can be seen that you didn't give enough interest to the base forms (cranium, rib cage, pelvis) or other elements like the tiger's toes.

You can also notice a lack of planning when drawing the fur of the dog and the cat in the last drawing.

When you want to represent the texture of an animal, you should analyse it beforehand (as in the texture exercises in lesson 2) and capture what you understand.

Within this course, using hatching or random lines shows that you have not analysed the texture of what is in your drawing.

Conclusion:

I will leave some homework for you to work on the things mentioned.

Don't be discouraged if you feel there is too much to correct!

You also did some great things like drawing animals in full motion or in pairs. Both have a unique touch!
