Hello MsPurrr, thank you for replying with your revisions.

Organic forms

Most of these are pretty close to simple sausages, good work. The form at the top left of the page is swelling through its midsection and becoming bloated, so that's something to keep an eye on.

Your contour curves are mostly looking smooth, an you're doing a good job of hooking them around the form so that their curvature accelerates correctly. Keep in mind that you should be varying the degree of your contour curves, just like you varied the degree of your ellipses. You can see a good example of how to vary your contour curves in this diagram showing the different ways in which our contour lines can change the way in which the sausage is perceived.

Insect constructions

Your shrimp and lobster demo drawings came out well, I can see that you've followed the steps shown quite carefully.

Your weevil construction has a good sense of volume, we can tell that the insect's head is closest, with the thorax and abdomen receding behind it. You're showing a developing understanding of how the forms you draw exist in 3D space, good work.

I do have 3 points for you to keep in mind as you move forward, and I've marked them on your weevil for clarity.

• It is good to see you making use of centre lines to help clarify the alignment of your forms. Keep in mind that insects will usually be symmetrical, and you can use this to help place your centre lines correctly.

• There are a number of places where you've extended the construction with partial shapes, I've marked 2 examples in blue. It is difficult for the viewer to understand how these additions are supposed to connect to the existing forms in 3D space, so they will feel flat. Instead we draw complete forms with their own fully enclosed silhouettes, establishing how they connect to the existing forms. I've drawn some examples in red for you. This is the same as what you were doing when you followed along with the shrimp and lobster constructions, and as is shown in the ant head demo I shared with you previously. Take a look at this diagram which shows the various types of actions we can take on a construction, using the context of a sphere. When working on organic constructions in this course you should strive to only take actions by adding in 3D. as shown in green in the lower right.

• You're making progress with your leg construction, I can see you applying some elements of the sausage method in your work. The method is quite specific, and there are some ways you could be following it more closely. 1- stick to simple sausage forms for your armatures, as closely as you can. They should have round ends of equal size connected by a bendy tube of consistent width. I've redrawn a form in green where it looks like you deliberately deviated from these characteristics in order to get your form to capture more of the leg in question. We want to keep the sausages simple, as this will help them to feel solid and 3D. 2- remember to include a contour line at each joint, to show how the two sausage forms intersect. This will reinforce the solidity of the construction. 3- Once you have the simple sausages in place, then we build out any lumps, bumps, and complexity as needed, using complete 3D forms with their own fully enclosed silhouettes.

Oh, and this isn't marked on your work, but make sure you remember to draw around your ellipses 2 full times before lifting your pen off the page, as this helps to execute them smoothly. It looks like you stopped short of 2 passes on the abdomen of the spider and the thorax of the weevil. This is something we ask students to do for every ellipse you freehand in this course, as introduced in this section.

All right, I think that covers it. Your constructions are heading in the right direction so I'll go ahead and mark this lesson as complete.

Please refer to this critique as you progress though the next lesson. The points discussed here will continue to be relevant to animal constructions, and the advice and diagrams I've shared here should help you to tackle them effectively.
