Starting with your organic forms with contour lines, one point that you've overlooked definitely stands out - you don't appear to be trying to stick to the characteristics of simple sausages. It is important to review the instructions of the exercises periodically to make sure you're practicing them correctly.

The contour lines themselves are looking good, although watch the spots where you attempt to immediately redraw them, or parts of them. Correcting mistakes is a bad habit, because it breaks the rules of the ghosting method, causing us to draw more reflexively rather than planning and preparing before every stroke.

One last thing - make sure you're shifting the degree of your contour curves as you slide along the length of a given sausage/tube form. While this is mentioned in the notes for this exercise, I've recently updated the Lesson 1 ellipses notes and video to better explain why this occurs.

Moving onto your insect constructions, I can see signs that you are developing in the right direction - you're thinking about how the constructions exist in 3D - but overall you are definitely leaning more into taking steps that prioritize the end result rather than focusing on each drawing as an exercise in spatial reasoning. One example of this is how in this drawing you blocked in the initial masses really faintly, as though you weren't quite committed to them existing in the world as solid, 3D forms.

Those initial masses are very important - accepting them as solid, tangible forms gives us a structure upon which we can begin to build the rest of our structure with more forms. Your drawings tend to deal more in putting down individual strokes, rather than building up complete, enclosed forms. As a result, as the viewer we're often reminded that we're looking at a drawing on a piece of paper, made up of lines and shapes. The goal here is to learn how to work in form, in 3D space, to not only fool the viewer but also to fool ourselves.

Take a look at this lobster demo and note how every phase involves commitment. Every form added to the scene is treated as though it's real, tangible. Any action I take is in 3D, wrapping forms around one another, establishing spatial relationships. I'm not sketching, nor drawing, I am constructing.

Since you're generally more invested in creating a nice drawing, when you get into the detail phase you have a tendency of thinking more in terms of "decorating" your drawing, to make it look good.

What we're doing in this course can be broken into two distinct sections - construction and texture - and they both focus on the same concept. With construction we're communicating to the viewer what they need to know to understand how they might manipulate this object with their hands, were it in front of them. With texture, we're communicating to the viewer what they need to know to understand what it'd feel like to run their fingers over the object's various surfaces. Both of these focus on communicating three dimensional information. Both sections have specific jobs to accomplish, and none of it has to do with making the drawing look nice.

Always focus on how the marks you put down on the page communicate with the viewer - how it conveys information about form, things that exist in 3D, things that you can feel with your hands and fingers, rather than simply things you can see with your eyes.

While this drawing does have some of the issues I mentioned, it's definitely a big step in the right direction. You're clearly thinking more about how forms wrap around one another, how the forms relate to one another in 3D space. Your linework is still a bit loose, and your general approach is more about exploring and sketching, rather than constructing with the kind of intent and forethought that we're after.

This means you're headed in the right direction, but you need to reframe your approach and how you think about what you're doing here. I'm going to assign a few pages of revision, so you can demonstrate your understanding of this. I strongly recommend that you study that lobster demo carefully.
