Markmaking: You are doing good with this. It's on the right track. I can see you struggle more with curved lines which is normal. Just make sure markmaking is part of your warm-up routine and your lines will become tighter and your confidence making them will grow.

Rotated Boxes: Great job keeping the lines tight together. You also good a wide range of rotation which is a big part of the exercise. It might have been a better idea to go over the outer lines of your boxes more, rather than doing the cross-hatching. I think that with the cross hatching you were trying to separate your boxes for the viewer, but in many ocassions it just adds noise and makes a specific area hard to read. This happened mostly in the places where you struggled to find the right line for the back inner end of some of your boxes. If you really like crosshatching that's cool, but try using it selectively, just because you cross-hatch somewhere doesn't mean you have to do it for the whole figure. Use it to your advantage.

Organic perspectives: You need to rotate your boxes more. I can see you realized that and tried to do it in the next pages. It didn't really worked because you often ended up with very similar boxes, but I can see you saw your problem and tried to fix it, which is good. You made progress in the last page, but remember to draw through your boxes to really practice. If you're having trouble rotating your boxes that's totally normal and it just comes with practice and experimentation. The 250 box challenge is good for this, obviously.

Ellipses in planes: You achieved the purpose of this exercise. I don't really have much feedback for this one

Funnels: You are having trouble drawing the shape of the ellipse and keeping it centered. If I were you I would give priority to practicing this more because feeling comfortable drawing ellipses in various angles is something you definetively want for the next lesson. Don't think that you have to master this before moving on. Remember that you don't have to master anything at this point before moving on. Keep an idea of the bigger picture of this course and why you're doing it

Plotted perspective: Not much to say here either. Looks tight.

Rought perspective: Good eye, I feel you got the point of the exercise. In general, remember that with perspective the lines dont have to converge perfectly to convince the viewer, they just have to feel right. The lines around the line you want to draw are your guide.

Good work in general, congrats on finishing this lesson. Constancy and discipline are important. Keep it up! :)

You asked in a discussion board why you don't have a badge for this lesson. I suspect the person who critiqued you forgot to mark it as completed. I think they did a great job with their input and agree with them that you are good to move on. So I am marking it as complete to see if this solves your problem.
