Looking over your work for this lesson, I think it's quite clear that you've grown a great deal throughout the set, and you've shown a great deal of tenacity and patience towards the end when it comes to just how thoroughly you end up subdividing your constructions. You're demonstrating a clear willingness to really dig deep into the structure of all of these objects, and I'm not seeing you cutting very many corners or taking shortcuts when it comes to the object constructions, and that's fantastic. There are a couple places where you probably could have gone a little farther, but I can count them on one hand. Overall you've done great.

Starting with your form intersections, my only real concern here is that your linework appears to be kind of shoddy. It really is just a matter of taking more time to work through the planning and preparation phases of the ghosting method. Don't forget to draw through all of your ellipses - including those defining spheres - two full times before lifting your pen. And of course, execute those marks from your shoulder consistently each time. The process you're employing for your forms here is all correct - it just requires a bit more time. That's really the big distinction - later in the lesson you show far more willingness to work through problems, giving them the time they require, rather than completing the tasks in the amount of time you feel to be suitable. Doing the same in your form intersections would yield considerable benefit as well.

So the main area where I saw a few steps that were skipped was when you were placing some of your ellipses. So for example, if you look here I've marked out places where you could have subdivided your planes a little further to find a more specific location for your ellipses. Instead of having them float more arbitrarily, we can set out their boundaries so when we do draw the ellipses themselves, we know exactly where they need to fall. You did this more correctly with your screwdriver's handle, where you established planes for most of your ellipses. I get that you weren't able to place ellipses in them perfectly (likely due to the restrictions of your ellipse guide), but you got them plenty close enough.

Beyond that, I really don't have any complaints. You're working through the steps conscientiously, and you really don't appear to be afraid to subdivide things further when you feel it'll help. So, instead of dragging this critique any further, I'll go ahead and mark this lesson as complete. Keep up the great work - your patience will serve you really well when you hit the last lesson, as it will be demanding in all the same ways, just taken to a much further extent.
