I believe I can offer some help with the form intersections exercise. When you first draw your forms on the page, there is really nothing indicating where they are in space next to each other. When you draw in the intersections, you are clarifying where the shapes are with respect to each other. If you are struggling with how the shapes intersect, remember that the intersection of two three dimensional shapes forms a two dimensional shape as Uncomfortable demonstrates here in the instructions for the homework:

  • The intersection of two planes is a line, and a box is just a set of six planes

  • The intersection of a plane and a sphere forms an ellipse

  • The intersection of a plane and a cone forms a conic section

  • The intersection of a plane and a cylinder forms an ellipse (or a rectangle, if the plane is parallel to the axis of the cylinder)

The intersection of two curved forms is more complicated, but try to remember that it will be circular in nature, regardless of if the shape is a cylinder, cone, or sphere.

A few other critiques:

  • I see you are drawing in a sketchbook. While this is fine, make sure that it is a sketchbook meant for pen and not pencil, as indicated in lesson 0. Also, you appear to be doing the lessons on back-to-back pages, and the ink is bleeding through, making your lessons appear less clean. In the future, please complete your lessons on their own sheets of paper to avoid the bleeding.

  • I see you are using hatching as shading to help define your forms. Uncomfortable recommends using only cast shadows, as indicated here in lesson 2.

  • In your organic intersections, the shadows are attached to the shapes casting them and it is causing your shapes to all kind of melt together. Try to keep the cast shadows separate from the forms that are casting them.

And finally, if you have questions or are having trouble getting your work critiqued, do not be afraid to reach out for help on the discord!
