Starting with your organic forms with contour lines, these are generally looking pretty good. There are some small ways in which you're straying from the characteristics of simple sausages - a couple having ends that are different sizes, and some having ends that are a little more stretched out instead of remaining entirely circular - but as a whole these are well done, and your second page definitely appears more confident than the first.

Moving onto your insect constructions.... honestly, I'm kind of hard pressed to find anything to critique. You've done an excellent job, and as far as your capacity to think and see in 3D, I think you're making considerable progress. That is ultimately what is most apparent here - you're building up your constructions piece by piece, and every new component you add helps reinforce the illusion that the whole construction is 3D, simply by defining the relationships between those 3D elements. Simple things like designing the silhouettes of your added forms to establish how they wrap around existing structures goes a long way to keep pushing that illusion forward.

You're also holding true to the premise of building from simple to complex - many students would have tackled the rhinoceros beetle's horns in a single go, capturing both prongs in a single form, and I am thrilled to see that you built your way up there, first with the overall structure, then adding two separate prongs on top to finish it off.

Now there are areas where you did have some weaknesses initially, but steadily improved upon them. For example, you were definitely struggling to build up additional masses on the ladybird's legs, but you managed it much more convincingly for the honey bee soon after.

As far as that goes, your approach is working, but I would generally recommend avoiding the "sausage in a hotdog bun" look where possible. Instead, try to have your additional masses kind of twist along the length of the underlying sausage structure, as shown here. Even if it's a subtle twist, try to avoid the straight border right down the length of the sausage.

For the most part you've done a pretty great job of sticking to the sausage method. The only place you really deviated was with the grasshopper's back legs. I understand why you did so, but in general it is always best to look at the sausage method as laying down a base structure or armature for the leg, so it can be used in all possible situations (and should be at least within this course). Since you can build right on top of it with new additional masses, you can still achieve any structure you need after the fact. It provides a starting point that maintains the illusion of gesture and solidity in equal measure, making it a very useful tool.

The only other thing I can think to call out here is that I think in this ant you may have gotten a little too enthusiastic about establishing line weight and cast shadows, and probably ended up jumping into it too early. Always leave that stuff for the end.

With that, I'll go ahead and mark this lesson as complete. Keep up the fantastic work!
