Hello Drego47

Starting with your organic intersections I'm happy to see you're drawing through your forms, and they're all slumping and sagging with gravity now, well done . I think it will take you some practice to get used to thinking about how these forms exist in 3D space, so you can wrap them around each other without making the forms too complicated or confusing yourself. I'll leave you to practice this yourself, in your warmups. When you do, be aware that this exercise yields more benefits if you make your forms roughly equal in size, rather than the big momma and her babies arrangement you have on your page.

Moving on to your animal constructions

Observation- I can see a notable jump in your accuracy compared to your initial submission. There are still some issues (the cat's neck is angled about 30 degrees left instead of straight up, and is probably 50% longer than it should be) and everything is still oversimplified, but this is a big step in the right direction. Keep working on developing your patience and extracting information from your reference instead of relying on memory. Make sure you're using the ghosting method in full for every line your draw too, some of the lines for your additional masses, for example, are pretty wobbly.

Major masses- You did a good job remembering to connect the cranial ball to the torso in all of these, well done. Remember that the rib cage occupies roughly one half of the torso length, as explained here The cat is close enough. The other constructions your rib cage is too small and/or misshapen. I've made a correction here on your rat. Also a reminder to connect your tail, otherwise it will read as a flat shape instead of a 3D form.

Legs- Perhaps I was remiss not to go into this in depth previously, but my critique was already very long and detailed. Basically you had applied the sausage method correctly on some of your constructions, like this fox but not all of them. I did make corrections to your legs on your goat and your bat but I didn't really explain what I did or why.

You want every sausage in your chain to be a complete form. This includes the upper one that connects to the shoulder or thigh mass. Draw the whole sausage form, then intersect it. I've marked on your lamb what I mean. I also did a very quick suggestion for tackling cloven hooves. As well as a tip for shoulder and thigh masses- making them bulkier with give you structures to wrap your masses around. Speaking of masses...

Additional masses- I'm happy that you've stopped adding extra contour lines to try to fix them, good job. You're showing that you still need some practice to understand how your additional masses exist in 3D space and interact with the underlying structures you've already drawn.

"One thing that helps with the shape here is to think about how the mass would behave when existing first in the void of empty space, on its own. It all comes down to the silhouette of the mass - here, with nothing else to touch it, our mass would exist like a soft ball of meat or clay, made up only of outward curves. A simple circle for a silhouette.

Then, as it presses against an existing structure, the silhouette starts to get more complex. It forms inward curves wherever it makes contact, responding directly to the forms that are present. The silhouette is never random, of course - always changing in response to clear, defined structure. You can see this demonstrated in this diagram."

You're making your additional masses a bit less round and blobby than you were before, but a lot of them look thoughtless or random.

I've made some notes here on your rat where your masses were illogical or random, as well as noting in green a section where you did a good job.

And some more notes here on your wolf. Please study them carefully, they're designed to help you think, and to understand what you're supposed to do. If you you don't understand what I've done, or why, please ask for clarification.

Finally, heads- You're deviating quite substantially from the informal head demo that I asked you to follow. None of them are complete, and I've done a side by side comparison here on your wolf, to demonstrate how you're pretty far off base even with the first couple of steps that you do attempt to follow. You need to define the brow ridge, forehead plane, cheeks etc, but to be blunt I'm not going to spend my time demonstrating something that you're not even trying to do.

Sometimes it seems like it's not a good fit for certain heads, but as shown in in this banana-headed rhino demo it can be adapted for a wide array of animals.

I won't be moving you on to the next lesson just yet.

1-Keep working on your patience, planning and observation, this is improving, but I don't want you to drop the ball on it.

2-Remember the basic proportions for your 3 major masses.

3-Use the sausage method of leg construction in full, as I showed you.

4-Think about your additional masses before you draw them, they're not random.

5-Follow the instructions in the informal head demo.

Please complete 5 pages of quadrupeds. Please continue to stick to the following restrictions:

1- Don't work on more than one construction in a day. You can and should absolutely spread a single construction across multiple sittings or days if that's what you need to do the work to the best of your current ability (taking as much time as you need to construct each form, draw each shape, and execute each mark), but if you happen to just put the finishing touches on one construction, don't start the next one until the following day. This is to encourage you to push yourself to the limits of how much you're able to put into a single construction, and avoid rushing ahead into the next.

2- Write down beside each construction the dates of the sessions you spent on it, along with a rough estimate of how much time you spent in that session.

Best of luck!
