You definitely do make a fair bit of progress over the course of the lesson in applying the principles and demonstrating an understanding of how your forms exist in 3D space, and how to combine them to construct more complex objects. That said, there are a number of places where you don't really adhere as closely to the instructions as you ought to, and it definitely has an impact.

While it's not as important, the first sign we see of this is in your organic forms with contour curves - specifically the fact that you've neglected to draw the central minor axis line. Overall they're not badly done, but there are a few other issues as well:

• The alignment of the contour curves has minor deviations (of course that minor axis line would have helped with this)

• You're not always sticking to the principles of drawing simple sausage forms. That is, two equally sized spheres connected by a tube of consistent width. This is very important as the simplicity makes them much more effective tools for construction, as any further complexity undermines the solidity of the form.

• While in most cases you're doing a good job of wrapping the contour line around the given sausage forms, there are definitely a few where your contour lines are drawn more lazily, and end up being too shallow in curvature to properly hook back around. The big one in the middle-right of the first page definitely stands out as one of these.

• For the most part, it doesn't look like you're applying an appropriate shift in your curves' degree along the length of your sausage forms, which causes them to look somewhat more stiff. Remember that the degree will change as it represents the relationship between the orientation of the cross-sectional slice and the viewer.

Moving onto your insects constructions, you did a pretty good job of following along with the demonstrations, though one thing that did catch my eye was that the marks you put down, though they were drawn confidently, did feel just a little bit rushed. It seems as though they could have used a little more forethought and planning preceding the nice, hesitation-free execution. This would have improved the accuracy of your results, though it certainly would have taken more time.

I am honestly very pleased to see just how big you've taken to drawing - it helps engage your brain's spatial reasoning skills quite effectively, and allows you to sort through the construction problems well.

Looking at your ants, the first thing that jumps out at me is that you're employing some well developing (if again, slightly sloppy) construction along the heads where you've drawn a solid ball for the cranium and then added form and volume to it. As you continue to move forwards, try and actually define the connections between the forms you add on top, as shown here. The two protrusions along the either side of the back of its head need to have clearly defined relationships with the rest of the construction so we can understand how all these forms relate to one another in 3D space.

Currently, while you're on the road to applying effective construction, I still get the impression that you're at least somewhat thinking in terms of how the things you draw are just flat shapes on the page, and that you're tricking the viewer into believing that they're three dimensional. You don't quite believe in the lie you're telling, and that leaves you open to putting marks down that contradict that illusion, and undermine the viewer's suspension of disbelief. For example, we can see how in that same head, some of the cranial sphere's mass pokes out from underneath the rest of the construction, just floating there arbitrarily. If we want the construction to feel entirely solid and believable, we need to make sure that we treat the things we draw as being three dimensional, not just lines on a page.

Another point I Wanted to make was that you're not quite employing the sausage method correctly in these drawings. You apply this to varying degrees throughout your homework, but you aren't quite keeping to the very specific requirements of this technique. The technique itself is extremely effective at capturing both the illusion that the forms are solid and three dimensional, and the impression that they're flowing and gestural, as limbs ought to be. The requirements help us to achieve this illusion, and neglecting any of them undermines those goals:

• The sausages must be simple - each individual sausage being like two equally sized spheres connected by a tube of consistent width. The different sausages don't need to be the same size.

• The sausages must overlap/intersect enough to have a solid, grounded relationship

• The connection between the sausages must be reinforced with a single clearly drawn contour curve. None along the length of the form, as they won't be necessary - this contour line will define the relationship between the forms in 3D space, creating a recursive link between them where if one form feels three dimensional, the other will automatically.

You may look at an insect, or an animal, and think that its legs do not look like a chain of sausages to you - but that doesn't matter. This technique produces an underlying structure or armature onto which further masses and forms can be appended to bulk things out where necessary. It is, however, an extremely effective starting point.

Now, all things considered, your overall grasp of form and construction has improved a great deal over the course of this set, so I am still comfortable marking this lesson as complete. Above all, make sure you put more effort into following the instructions as they are written in the future. If you haven't done a certain exercise in a while, reread those instructions to make sure you're not spending time doing things you're not meant to.

And goodness I hope you can wipe that spider drawing off your desk.
