There is improvement in some areas, but there are still issues that I'm seeing. When it comes to being more mindful of how some of the additional masses - specifically those along the backs of your animals - wrap around the underlying structure, you're certainly getting better.

I also think that you're dropping the ball when it comes to observing/studying your reference in certain areas. Specifically, the front legs of some of your animals, like the wolf, the puppy, and the fox appear to have no knees.

Looking at the wolf specifically, I went over it and pointed out a number of issues here. The back half is honestly pretty well done. It is a bit simplistic, in that the legs specifically still stick to a lot of the bare bones sausage structure, though I can see y ou attempting to make some small attempts at building up complexity on top of that armature. You can see an example of how much farther that kind of structure can be taken here.

The front half of the wolf goes all kinds of wrong though. You're drawing the ribcage way too small (I mention here that it should be half of the torso, you make this mistake pretty frequently), the knees are missing, and the proportions feel quite off.

Additionally, when drawing the head you tend to overlap the eye socket right over the muzzle. Instead, you should be treating them like pieces of a 3D puzzle (I mentioned this in my previous critique) where they fit together cleanly, not overlapping one another. The intent is not for them to float arbitrarily, but rather to have clear spatial relationships against one another.

One of the reasons these drawings are expected to take so long is because the vast majority of our time really is spent studying and observing our reference image, to understand all the different forms that are present, what the major forms are, and how they exist in proportion to one another. Then we continually go back, after every single form we construct, to ensure that we're not working from memory, but that we are doing our best to capture what is present - not what we think the animal looks like.

You're making progress, but you do have a ways to go. Take what I've mentioned here and do another 4 pages, keeping these points in mind. When you submit the next 4, include your reference images, as they can sometimes be helpful in understanding why you may have made certain choices that aren't immediately clear otherwise.
