Hi there again, and no worries! I'm glad I could help!

Good job on the animals, I think you are making good progress, these new ones look way more solid than the others!

Nevertheless, there are still a few issues I can see so I'm going to point them out as best as I can, here we go:

I'm gonna go over each drawing one by one:

Here are the notes I noted on the wolf, I'll go over them one by one, marked 5 numbers on the picture circled so hopefully it's easier to follow.

1. Eyes. When drawing eyes, you tend to use a ellipse to map then down and then jump to the eyes. Never do that. Always follow the steps I wrote on the notes:

1. Cut into the form of the cranium with simple straight lines to clarify how the eye socket is in 3d space. 

2. Add an eyeball, this time drawing through 2 times a sphere. 

3. Now, taking in mind the form of the eyeball, add the eyelids just like I did.

2.Sausage forms

This is something you too repeat over the drawings. For legs, always use sausage forms. Never use flat shapes like you did some times on the elephant or the wolf, always simple sausages, that is, 2 identical balls connected with a tube of consistent width

3.Initial contour line

When starting an animal, you should first draw the mass for the pelvis and the mass for the ribcage, then you shoud join them with a sagged sausage.

After you do that, you need to add an initial contour line , just like I did in orange. When adding adittional forms to the torso, they will have to follow that contour line you drew, as it defines the perspective of the torso.

4.Additional forms and intersections, when adding adittional forms, try to think like in the form intersections exercise; they have to wrap around the forms you are adding them to. This is something that you do way better on the elephant, so I can already see improvent! But try to keep it in mind as you keep doing more of these drawings, approach them more like you did in the elephant.

Intersections Always, in all your drawabox drawings, you should make clear how each form intersect, for example in the part I marked, you didn't draw the intersection between the leg and the paw, so that relationship wasn't clear. You did that as well on the tail, there should have been an intersection between the tail and the body.

5.Drawing through your forms Always too, draw through your forms. In the example I noted you didn't draw through the back leg for example.

The camel feels really solid, good job! The issues I can find on it are only that you didn't draw through your forms, like in the back legs for example, and the use of addittional forms. I noted them all here

And lastly, the elephant, marked here the notes, felt pretty solid in general! again, lots of improvement!

Heads constructions look good in general except that you used an ellipse for the eye socket in some of them.
