Good job on completing the revision!

Overall you did the exercise correctly, however I should have probably been more specific in what I meant by round-on-round/flat surfaces. This basically means all the intersections but focusing on ones that create the round and flat ones. For example a cone and a sphere, a sphere and a cylinder, cylinder and cone etc. not just spheres and boxes. This only limits you to 2 intersections and doesn't really challenge your spacial reasoning skills because you are essentially just repeating the same intersection over and over. For the intersections themselves I noticed you tried surrounding the boxes with spheres which ended up creating impossible / "see through" intersections. This basically means you draw intersections where you can't see them. This is a good exercise once your spatial reasoning has advanced to the level where form intersections is easy but for now try to only do intersections which the viewer (you) can see. Finally, while the lines for the boxes and outer part of the sphere are certainly confident, the intersections themselves become very messy due to the repeated line work which tells me you aren't really ghosting that much and are instead re-drawing the lines based on instinct. Every mark done in the drawabox course should be thought out and deliberate by ghosting many times and thinking before hand. Additionally the lines on the boxes themselves are diverging which is impossible for a box to do.

I won't assign revisions as the major errors are from different lessons, however I strongly recommend you take a look at the box challenge and lesson 1, focusing specifically on line work and boxes. As you mentioned in your other reply, since you've been doing drawabox for a couple of years now you probably haven't done warmups consistently for those years but even just 10 minutes a day can go a long way.

About the stuff you wrote on AI, I actually thought it would never be able to be automated but it was actually one of the first things to be automated which is quite interesting. Because of this more and more artists have been posting less and less which is disheartening and depressing as people are accepting that they will lose their skills to AI. It would be nice if society shifted from a labour to leisure economy but I think that is still far off into the future, probably when AGI is developed as the current narrow AIs won't be able to replace every job (probably?).

Anyway, congrats on completing drawabox! If you have any questions don't hesitate to reply.
