Hi Gashif! I'm going to go through your submission.

Starting out by your sausages, I think you are doing a good job in here, though there are some things I wanna call out:

• First, although you are doing a good job with those contour curves and it's okay that you draw a little more of the ellipse so you can feel the curve, though remember that you should try to slowly adjust that so you don't go so much over the other side of the form. Take a look at this contour curve you did, it's almost a full ellipse! So, it take time, but always strive to getting better at doing the contour curves more acurate and less like the full ellipse.

• Another issue is that, even though you are varying the degrees of your ellipses (which is great!), you can push it futher to create more solid and create a better illusion of depth. Remember that contours curves/ellipses represent how a cross section of the form faces the viewer, if it's narrower it's turning aways, and if it's wider it's facing the viewer. Here is a diagram on the topic!

• One last thing, be ware of accidently flattening your sausages with ellipses or contour curves, see this one for example, I know you are trying to show that the sausage is facing us and then down, but what happened was that it looks more like a flat sausage. So, it's perfectly fine (and encouraged) to take a little time to think about how will that contour is facing the viewer.

Moving on to your constructions, I think you are doing a good job taking into account all forms as 3d, though there are some things I want to draw attention to so you can keep on the right track.

A very important thing about drawing and what we try to do on this course, is that we try to draw 3d solid forms, in a 2d serface (our page). What this means is that is very easy for us to do lines that follow a 2d mindset and turn out undermining our constructions- To avoid this kind of lines, we can set up some rules to follow, so we can keep on the 3d side.

One of this rules is to never directly alter the silhouette, this means both cutting into it and also expanding it. The issue here is that silhouettes are 2d shapes that represent the 3d forms, and the thing is, that if we just alter the 2d shape, this will not mean that it will also change the 3d form, what it does is that it just breaks the connection between shapes and form, and ultimately breaks the illusion, making the viewer remember that they are just looking at a 2d drawing.

To set some examples, here are two constructions where you are both cutting into the silhouette of your base forms (crab) and also expanding it so you can unify two forms (mantis).

Instead of doing this, what we do on DaB is to work additively, this means that we try to construct on top of our forms and we ramp up the complexity by introducing new, solid and 3d forms that stack on top of our base structure and then we clarify those relations by wrapping them around each other like this! or intersecting (like the lesson 2 exercise). While you are doing it most times (a good example is your beatiful lobster), you need to stick more strictly to it, here is an example applied on a beetle horn and here is one applied on an ant head.

Another thing that I'm seeing and you noticed, is your line quality- This is one of those things that we need to consciously always go on for a long time until we can do it without thinking. So, until we get to that far away goal, I encourage you go back from time to time to the principles of mark making, it's always good to remember what we need to take into account when we are doing lines!

One thing that called my attention was the way you are applying line weight through your constructions, what you are doing in a lot of them (if not all) is that you are using it like a clean up pass all around the silhouette of your forms. Now, not only you are just working on the 2d silhouette (which is somehow related with what we've already talked about), you are using line weight wrongly- Line weight is a localized tool that we use to clarify how our forms relate to each other in specific areas, by using it all over the drawing, you are undermining the strengh of those lines that are meant to clarify overlap.

On the same note, you are still kind of doing clean up passes with your lines, although you improved since last lesson, it's still something that is happening, so keep an eye on it!

Lastly, good job on applying the sausage method for the legs, though you can still build on top of this sausages with more forms, in order to create a more solid sense for them, like this. For some examples, here is a demo from Uncomfy where he makes a more solid and complex ant leg by adding forms to the sausages!

So, while I have give you quite a few important concepts to work on and keep in mind, you are still doing a very good job on this constructions, so I'm gonna go ahead and mark it as completed! Keep up the good work.
