I think this is a really good question ( and I have been through this exercise but still struggle with the concepts ).

It's so close to being all on one plane with no hard edges that I would say they were form shadows. However I could make an argument for cast but it would be weaker. If the paper was more severely crumpled so there were more acute planes then it would be easier.

I'm not sure whether this image perhaps has too diffuse light to differentiate clearly. It there was just one distinct light source it might have aided discovery.

I will be following any other responses with interest.

Thanks for the answer, I will try to find a better image, I am trying to find the cast shadows, am I correct?

This is all in my opinion, not necessarily canon.

It is implied as cast shadows in the text. I think this is something to understand but not to overly concern you. Cast shadows tend to be the very dark shadows that have clearer definition, form shadows are more diffuse. So when you are drawing texture you have to decide which shadows are significant in depicting it. These will generally be the cast shadows because of their nature.

I tend to look at the image and try and decide what the cut off value is for where a shadow is depicted or not depicted and then render them. Give or take and allowing for hue.

I think your attempt above is good. The big benefit of this lesson is learning to closely observe what is going on ( it has helped me enormously ) but it does mess with your head if you let it. Push through, do your best, then get some feedback is my recommendation.

A lot of my students use these. The last time I used them was when I was in high school, and at the time I felt that they dried out pretty quickly, though I may have simply been mishandling them. As with all pens, make sure you're capping them when they're not in use, and try not to apply too much pressure. You really only need to be touching the page, not mashing your pen into it.

In terms of line weight, the sizes are pretty weird. 08 corresponds to 0.5mm, which is what I recommend for the drawabox lessons, whereas 05 corresponds to 0.45mm, which is pretty close and can also be used.
