Starting with your sausages , you could try to stick more to the characteristics of simple sausages. It's just a little detail and doesn't really stand out much but there's place for improvement. You did a good job with the contour lines they fit snuggly within the sausages but one important thing to notice is the degree of the contour lines as in most of your sausages is consistent throughout the entire form. I suspect this is simply something you're going to have to think on a bit more actively when doing this exercise.

Continuing onto your insect constructions,I can see a number of examples that clearly show a good grasp of how the things you construct exist in 3D space, specifically in terms of having forms wrap around those that precede them, building up your construction in a three dimensional manner.

Now, you did really well using the sausage method to build the insect's legs, but there are some things to notice,this method is initially about laying in a base structure or armature that captures both the solidity and the gestural flow of a limb in equal measure.

For reference take a look at this or this, the tarantula is the drawing where you can improve most by using this technique.

And finally, I noticed a handful of places where you tried to incorporate some form shading into your drawings here. As mentioned in the texture section here, form shading is not something we're generally going to be using in this course.

But overall it is a pretty solid submission so I'll mark it as complete.
