In regards to the ellipse guide thing, it's possible that you got one piece of a larger set, hence the limitation. A full ellipse guide can be quite expensive, so most students here will opt for a 'master ellipse template' - basically it'll have a lot of different degrees, but will be more limited in the overall size. It wouldn't have helped you for most of these larger drawings (that camera's lens would not have been saved), but a master ellipse template will generally be adequate for completing the wheel challenge, and for giving you a big leg up in the complex constructions of Lesson 7's vehicles. I definitely recommend you pick one up, as freehanding your ellipses is, as you can see here, a skill that students even at this stage need a lot more mileage with to be able to do consistently in all cases.

Anyway! Starting with your form intersections, your work here is superb. You're showing a strong understanding of how these forms relate to one another in 3D space, and through the intersection lines themselves are coming along very well. I'm very pleased t osee the attention to the corners of the various forms - how you allow those corners to create clear breaks in the intersection line itself, allowing for the trajectory to shift to follow the new surface, rather than trying to muddily transition from one to the other as one would if the transition were more rounded and gradual.

Continuing onto your object constructions, overall you're similarly doing a great job. You're showing considerable patience and care throughout the process for every single one of these, and while some of your ellipses came out pretty badly (lookin' at you, camera guy), what's most important is what you intended to achieve with every mark.

In that regard, I did actually notice that the steps you attempted to apply on that camera lens were potentially a little lacking - for example, you dont' appear to have consructed around a central minor axis line, which is a fairly basic component of construcing anything cylindrical. With the smaller dials along the top of the camera, I think you also tried to force yourself into the ellipses you did have access to, to the point that they ended up being a little too wide, which threw off the sense of perspective.

Aside from those few mistakes however, there's no hiding the fact there are other constructions where you absolutely blew that stuff out of the water. The game controller is definitely the most complex, and the one that received the most of your time - and for that, it came out fantastically. All the same, most of your drawings followed that same level of patience and care. Most people wouldn't care to push quite as far with the oven as you did, but you took the time to ensure that every single component was positioned in a specific manner - not eyeballing anything, but rather taking the time to subdivide as much as was needed to keep everything grounded and specific.

I did notice that in your iron drawing, you had a lot of lines that seemed somewhat extraneous. You benefitted from the fact that the ballpoint pen can make lines that are a little more faint, but all the same you should make sure that you don't put down marks without all the appropriate steps to plan it out. The seemingly extraneous lines are those that run diagonally from the bottom of the front to the top of the back. Being that they're straight, I'm kind of unsure as to why they came out that way - using a ruler would have allowed you to figure out what you wanted to draw ahead of time, rather than testing a bunch of different marks. Either way, though, this is certainly nitpicking and I didn't see any other such wastage of linework in any of your other drawings.

So, with that, I'll go ahead and mark this lesson as complete. Keep up the great work - as it stands, you're definitely going to knock the last lesson out of the park, but before we get there, you've got a bunch of wheels blocking your path.
