Starting with your organic forms with contour lines, you've done a pretty great job of sticking (for the most part) to the characteristics of simple sausages as mentioned in the instructions. Your contour lines are also showing a good grasp of how their degrees ought to change as we slide along the length of the form, and you're doing a good job of hooking them back around as they wrap around the form. You do however need to continue working on getting them to fit snugly between the edges of the sausage form to really sell the sense that they're actually running along its surface. Right now you do have a number of places where they fall outside the silhouette, or fall short of touching that edge. Continuing to practice the use of the ghosting method in this context should help you improve your overall control and accuracy, without hurting the confidence with which you execute the marks.

Moving forward, I think you are doing a great job overall of really understanding and executing these insects as being arrangements of individual, simple, three dimensional forms, and as a result most of your constructions come out feeling very solid and believable. You also handle varying their poses and orientations very effectively, maintaining a consistent look across, say, this set of ants. Regardless of how they're oriented, they still feel look entirely three dimensional.

There are a few suggestions I want to share with you, however:

• Firstly, there are some occasions where you don't quite take full advantage of the space available to you. For example, these drawings are definitely on the smaller side, and they start getting into the territory where drawing smaller can limit our brain's capacity for spatial reasoning, and also make it more difficult to engage our whole arm while drawing. Your constructions are still pretty well done, although these are risks to keep in mind. Draw bigger, wherever possible - even if it means that you can't fit as many drawings to a page as you'd wish. Always focus on giving a drawing as much room as it requires, and only once it's done should you assess whether more can fit in the same page. If you suspect another will fit, go ahead and add it. Otherwise it's perfectly okay to draw just one on a page. In this case in particular, there was plenty of space left over, but I suspect you erred on the smaller side just to avoid a page with only one drawing (which again would have been fine).

• This is an issue I mainly only saw on the wasp in that page of particularly small drawings, but it's still worth mentioning. If we look at what I've marked here, you'll see that the red areas I highlighted are sections where you'd drawn a form on the page, but then cut back into its silhouette to "refine" its shape. As a rule, avoid modifying the silhouette of any form once it has been drawn on the page, and in the case that an ellipse is a little "loose" due to us drawing through it, always treat the outermost edge of the shape as being the silhouette of the form. Here's an explanation as to why cutting back into forms actually risks flattening them out, but this applies to extending that silhouette as well, as you did with the stinger at the base of the abdomen. Every alteration to a construction must be done by introducing new three dimensional forms and defining how they intersect, connect, or wrap around the existing structure. The stinger wasn't entirely wrong, but you missed the opportunity to define how that cone-like form would have actually intersected with the abdomen, with a contour line defining that relationship.

• As a whole, I am quite pleased with how you've adhered fairly closely to the [sausage method](), building your legs using segments that are almost exclusively simple sausages. Do however keep in mind that this is not always where legs begin and end. There will be inevitably circumstances where we want to build up additional mass on top of those structures, and we can do so by wrapping new, separate, three dimensional forms around that base sausage structure (using the methodology shown here and here). The sausages themselves only establish an armature, and we can take them farther if we wish as shown here with this ant leg. You'll notice there that there are all kinds of little subtle structures present on the ant's leg, and there are likely similar structures that could be explored in many of your own insect drawings. The same methodology can be used for animals, like in this dog's leg, and so this will come up a fair bit in the next lesson as well.

So! All in all I'm quite pleased with your progress, and am happy to mark this lesson as complete.
