Hello I'll be handling the critique for your lesson 4 homework

Organic Forms

-Starting with the organic forms I think you are doing a good job drawing sausages that have a consistent width, and when it comes to the contour curves they are also moving in the right direction, it seems that you are aware of the degree shift as they move through space, and they are also drawn with a good deal of confidence which has really helped to better capture their solidity. The only suggestion I have for you is that you could try different orientations for your sausages so you can take a look at this diagram which can help with that. https://imgur.com/CfKiLtt

Insects

-The insects are also moving in the right direction and in general you are making good use of the sausage method to break your subjects into their more primitive elements and building them step by step rather than trying to capture a lot of things at once. But let's see what things you could do better.

-You are doing a good job working with 3D forms rather than flat shapes and building on top of the main forms (head thorax and abdomen), the main thing I want to call out is the leg construction.

You are using the sausage method well in order to lay down a basic structure that captures both the flow and solidity of these limbs. However you can take it further, you'll see that the legs of most insects bulge in some areas, so you can keep adding more masses on top of it to better capture their actual shape.

Here is a diagram that shows this process applied to the leg of an ant

I did notice on your grasshopper that you tried to build on top of the back legs but you ended up modifying their silhouette rather than actually wrapping around new masses, so I will quickly redirect you to this diagram which shows how to add masses correctly https://imgur.com/t6oz7Tv, this is a something that applies to every aspect of the construction process not only the legs.

I think it is worth talking about this process more in depth given that you will be using it again in lesson 5.

Basically, whenever we want to build upon our construction or change something, we can do so by introducing new 3D forms to the structure - forms with their own fully self-enclosed silhouettes - and by establishing how those forms either connect or relate to what's already present in our 3D scene. We can do this either by defining the intersection between them with contour lines (like in lesson 2's form intersections exercise), or by wrapping the silhouette of the new form around the existing structure as shown here.

This is something that has not yet been fully integrated into the lesson material but you can see some pretty good examples on the informal demos page, the shrimp and lobster demos on the informal demos page use this specific approach, so give them a look and if you can actually draw along them would be very helpful.

-I also want to address your use of lineweight, it seems that in some areas you are using it to reinforce certain parts of the silhouette, instead it is better to reserve it for clarifying how different forms overlap, and it is better to avoid applying it on particularly long strokes as it becomes harder to control.

If you end up making it too thick it will end up taking the solidity of your forms away and turn them into mere graphic shapes.

-And lastly, I noticed that some of your drawings are somewhat small, so you could try to draw them as big as you can, this will give you much more room to work with which will make thinking about these constructional exercises much easier.

Okayyy , aside from that I don't have more to add so I'll go ahead and mark this lesson as complete.
