Looking at your revisions, there are a number of issues I addressed previously that are still present, giving me the impression that you may not have read through my critique as carefully as you should have. While I am sure this is not intentional, there are a lot of distinct points I raised that simply haven't been corrected, as shown here

A and B: You're still altering the silhouettes of your forms after they've been constructed. Every single addition to your construction should be through the introduction of a new, complete, solid, 3D form. You also cannot redefine/alter forms you've already drawn to make small tweaks in order to make them match your reference better. Treat the things you've drawn as though they're 3D, and they'll appear 3D to others. As soon as you treat them like they're just lines on the page, you'll remind the viewers of that fact as well.

C and D: You're still misusing line weight. The biggest issue here is that your use of line weight is basically resulting in you redrawing the silhouettes of your forms. Do not apply line weight so excessively - keep it limited to localized areas, and make sure you're using the same ghosting method to execute those marks. Don't trace hesitantly back along the length of your existing lines.

Additionally, I can see that you're trying to use the sausage method, although you end up redrawing the silhouettes of those sausages as well. Instead, draw the sausages larger, while maintaining the characteristics of simple sausages, and then build up new forms on top of them that wrap around those structures as shown here and here. You can also see this in action in this ant leg demo and this dog leg demo. The main issue I'm seeing stems from the fact that you're making the sausage structures so skinny that they don't actually play any role, you end up redefining their silhouettes anyway by engulfing them inside a totally different shape/form.

Lastly, I noticed a couple things to point out for your organic forms with contour curves:

• You seem to be placing contour ellipses on both ends of your forms, which suggests to me that you're not really aware or considering what they're actually supposed to represent. This exercise is just like the one with contour ellipses, except we're not drawing as though we have x-ray vision. So, while there's a full ellipse wrapping around the form for every contour line, for most of them we can only see a partial curve. It is only on the tips that face the viewer that we can actually see a whole ellipse - therefore you need to consider which end faces the viewer, and draw an ellipse there, rather than just putting an ellipse on each tip. Here are some examples of configurations where one end is fully visible to the viewer, both ends are, or no ends are.

• You're still not drawing through the ellipses you do draw. I raised this issue previously.

• Keep working on sticking to the characteristics of simple sausages - you're close, but you tend to have ends that are more stretched out rather than having them remain entirely circular, and you've got many that get a little wider through their midsection.

• As explained here, the degree of your contour lines should be shifting wider as we slide along the length of the sausage, away from the viewer. This is also explained in the Lesson 1 ellipses video, using props to explain why this occurs.

You have a lot of things to address, and I think you may be rushing a little and not quite giving yourself enough time to absorb what is being conveyed to you in the critique. As such, I'm going to ask that you complete the revisions that were assigned previously again, and that you submit them no sooner than one week from now.
