To start things off, it is recommended to start the 250 Cylinder challenge after finishing Lesson 5 because it fits in the later lessons, however if not, then you're free to do so.

For the revision, in the Form Intersection submission, I have not much to say since the intersection of forms are for you to decide, so a pass on that one. Lastly, the Counter Ellipse submission, it has improved with less errors, I suggest you to exaggerate the degree of the Ellipse, and make the ellipses of the degree not same adjacent to another. But a pass on that one as well, since warm-ups will help you get through this.

Regarding the Texture Analysis, I may have done a misstep on characterizing those grooves as hatching honestly, looking upon it more clearly, it is accepted. So I apologize for the blunder. However, if you want any suggestions, then take my advice with a grain of salt because you are free to convey on how a texture should look and appear, however, just to remind you on errors and reminders on how the course approach texture.

So, if I were to approach the armadillo scale (on the last square or panel), I would point the scale ends to the left because the light is going from East to West, not only that, because I assume that the groove shadows will not be visible. And because it has grooves there would be ripples like what you had done. Also another Example from the community:https://imgur.com/a/example-cF8gOIf. So this is a suggestion.

So basically, you can approach the texture on different ways, you can even discard my suggestion, and do the opposite, just do whatever it takes to achieve a texture looking like that texture, but I will remind you on how the course approach texture. Again I do apologize on the groove shadows categorizing those as hatching, and the texture itself is a pass.

I'll be marking this lesson as complete, since I think you got the gist of it, so Congratulations!1 you may now proceed to the next lesson.
