Hello and great day;

Ok first of all, I've noticed that there are some shaky lines in the organic lines so I'm not sure if you drew them confidently. I can also tell that you were great at using perspective; however, some of them appear to be off, but other than that, they're all superb.

Organic Forms, I'd say the contour lines were drawn well, as you can see from the curve degree, but I didn't see some of them with the contour ellipses. The sausages were drawn simply, to the point where I could say they were confidently drawn. I've also noticed that some curves undershoot or overshoot when using the contour.

Next, the texture analysis is excellent, but I believe you should try to integrate the texture further using the black marker in the right column.

The texture on the dissections is also really well drawn, and you did an excellent job slicing and breaking them through.

I liked how you executed the form intersections; they were much cleaner. However, I believe you prefer to overlap them with small groups, though they were all drawn confidently. I'm not sure why certain lines were put over them again, or if it's to demonstrate line weight.

On the organic intersection, I was a little confused by certain shapes that appeared to be drawn with foreshortening. It would be good if they could make the shadows more distinct and follow the contour of the sausages, like they did with their form.

Overall, you did a fantastic job with the exercises, despite the fact that I was also an amateur, therefore I believe you could now move on to the next lesson.

Arrow exercise

In this exercise, I can see that your lines are drawn with confidence and I can easily notice what you mean. However, I would be more aware of adding line weight, because sometimes you just draw another line instead of adding weight to one that already exists.

Organic Forms with Contour lines

In this exercise (especially contour curves) your lines turned out really wobbly. I think you forget to apply the ghosting method. I also don't want you to draw a lot of small organic forms. Make them bigger and more solid. I also have to point out that your curves are too shallow.

Contour elipses are a bit better, but sometimes your elipses are not rotated in the right direction, which makes your organic forms flat and hard to understand. However, good for you, lines are drawn with more confidence.

Texture Analysis

This exercise is great, I can notice that you understand the texture you were drawing. But you forgot to leave a white bar at the end of the transition part. Don't worry about that, it's not such a big deal.

Dissection exercise

This exercise is good, I can easily understand the message. I didn't spot any mistakes.

Form Intersections

As this exercise is meant to be extremely difficult, you've done a great job, especially on the box intersections. Thanks to you, now I know how it supposed to look like.

Organic Intersections

Here you repeated the same mistake that I've made on contour curves. Your curves are too shallow. Maybe you can look at them as halved elipses. Also, remember that what you constructed is an illusion of 3D world. Look at your page as a window. You're looking for a new, tangible reality.

Also, be more patient with filling cast shadows in black, because there are some unfilled spots here and there.
