I'm doing this course exclusively on my iPad Pro with an Apple Pencil 2 and Adobe Fresco. I drew this before watching the demo and now realize I was supposed to use the pencil point and shade with lines, rather than using the edge of the pencil to shade. I did draw the initial layout with straight lines, but I got carried away with the contours being a bit more curved. I also used more than 5 values . So...fail.
