Your superimposed lines look smooth and consistent. Most of your ghosted lines look straight and follow the correct trajectory. For the table of ellipses, you did a good job fitting the ellipses snug with in each section and their angles are mostly consistent. Your ellipses fit nicely in the planes and have minimal deformation. The spacing between ellipses in funnels is good and they are fairly well aligned with the minor axis. It looks like there may be some line corrections on your organic perspective exercise. I recommend more ghosting and aiming for one confident stroke. Accuracy will improve over time with practice. Overall, well done and I think you are ready to move on to the 250 box challenge.
