Starting with your organic intersections, your first page is admittedly seems to be a bit of a struggle. You're certainly thinking about how forms wrap around one another, but it certainly comes out feeling quite flat in places. Your second page definitely shows considerable improvement over this however, with the particular construction of each individual form feeling more intentionally planned in terms of how they exist in 3D space and how they interact with one another. If you haven't been keeping up with this exercise as part of your regular warmups (as you're meant to be picking two or three exercises from the lessons you've completed at the start of a sitting and doing them for 10-15 minutes), make sure you do so.

Your actual animal constructions throughout this lesson are actually fairly well done - to a point. You're following many principles of the lessons quite well, and you show increasing comfort with manipulation and combination of your forks to build up greater complexity in your constructions, although I think you have a tendency to stop a little too soon. That is to say, you leave your constructions fairly simple, when there's plenty more room for developing the subtler, more nuanced forms that are present along a given animal's body.

The short of it is that you're headed in the right direction, but you need to push yourself to go a little farther. So! Let's go over some different issues I've seen and how you can improve upon them.

Firstly, I noticed in your earliest drawing that you weren't drawing each and every form in its entirety, and instead were allowing some of them to stop where they were overlapped by another. As shown here, everything you add to your construction is itself a solid, three dimensional form, and we want to both draw them in their entirety and define their intersections with other forms in order to fully understand how they sit in space and how they relate to the forms around them.

Secondly, with the pups on this page you've got their torsos shaped with some pinching through their midsection. That sort of pinching (where the ends are larger and the midsection gets narrower) can serve to undermine the solidity of the form, so wherever possible try to construct a more even sausage form with a continuous width through its length, as shown here.

I also did notice that a lot of your drawings here were pretty small. Your brain's going to want more room to think through spatial problems, so drawing larger and making full use of the space available to you on the page will help as you sort through all these spatial relationships.

For the pup on the left side, you did employ the additional masses along its back quite well - it wraps around pretty nicely.

As we skip down through your drawings, when looking at your animals' head constructions, it does seem like you're somewhat more haphazard about which steps you choose to apply. Always try to think of these things as fitting a sort of formula - even if the different pieces and ingredients a different, they're being combined in a similar order. The key thing about the head is that it is like a three dimensional puzzle, with individual, solid pieces that fit together. You've got the muzzle, the cheekbone, the brow ridge, etc. and all of these pieces buttress the eye socket.

You can see demonstrations of this on the informal demos page - specifically the moose head demo and the tapir head demo. Notice how many individual forms I'm building onto there - it's not just a matter of putting down a couple simple forms and mushing them together.

The same can be said all over the body - where you are using a few additional forms here and there, there is much more that can be achieved. If you look at demos such as the puma, you're basically going through the first six steps of building out the body, and maybe the first couple of constructing the head, but then you stop there. There's a lot more to be done. Even to start, you can see a few additional forms you could explore along your hybrid's body.

Similarly, when it comes to the legs, you can see this comparison of a dead-simple basic sausage structure, and then all the additional forms that can be built up on top of it.

So! I've laid out a number of things you can explore, and I think I'm going to ask for a few additional pages below to help you demonstrate that you understand these concepts.
