Hi! Regarding your questions:

• On the running rat demo, you can see how to construct a muzzle in full profile. If you look at your fox reference, you can see that, even though he's on a full profile view, the different planes of the head are still visible.

• Yes, we fit the mass around pre-existing forms. I think Uncomfortable describes it as bags of flour; I tend to think of bags of flour when the masses are directly on top of things, and clay or sticky gum when they're below or around other masses; the point is that they have to wrap around the constructions. That rat demo from before is a good example of that.

Your constructions are looking a lot better, as is your line. In particular, your deer looks good, but you tend to slack off on the difficult parts such as feet, and you almost never add any masses to the head where they're necessary.

Remember that if you're going to use lineweight you have to ghost your lines the same way you would do it with any other line. Again, don't try to capture the whole image with a couple of forms, instead, build simple forms as an initial construction and then add masses to replicate those complex forms seen on the reference. This is something you tend to do, especially on the legs.

Here are the corrections for the fox. Most of the issues I see are addressed there. I think you're almost ready, but I'd really like for you to make another 2 animals.

One should be the same fox, and another non hooved quadruped. Think of all the corrections, and keep in mind the rat and the donkey demo when working. Treat the legs as carefully as any other section of the animal, and make those lines as confident as you can.

If you have any questions, I'll be around to answer them. Good luck!
