Starting with your form intersections, you've definitely got a number of really solid intersections here, though there is still room for growth in your understanding of the spatial relationships between forms. Here I've marked out a number of corrections. Note how I try and think about the curvature of the individual forms at the relevant areas (denoted by the arrows) and use them to determine what curvature the intersection should follow.

Continuing onto your object constructions, I think the methodology you've attempted to pursue here is very solid. You've shown a great deal of patience in subdividing your scaffolding quite thoroughly in a number of cases, which is an excellent sign.

I was especially fond of this space heater remote in particular. While you didn't get into the buttons, the care and fastidiousness you displayed in pinning down the specific curves of the structure yielded exceptional results. This is the kind of thing that product designers drool over. I can definitely see that you tried to apply similar care with your echo dot, but it seems that your ellipses fell apart here, which is unfortunate, as it was definitely heading in a solid direction. These things happen though, and I'm glad to see that you still continued pushing through.

For your switch controller, proportions were certainly an issue, but again - I am still pleased that despite seeing that the proportions were off early on (as I'm sure you did), you stuck to the structure of the construction and resisted any temptations to try and save it halfway through with dramatic changes. You held to the principles of construction, and for the most part your results did end up feeling quite solidly built, if wildly out of scale.

One critique I do have to offer about how you approached the controller is just with the pretty broad curving sweeps you have for the handles. They're not too bad, but when dealing with curves it is very easy to end up undermining the solidity of our forms the further we stray from the more straight-line based scaffolding, [as explained here](). Try to build your constructions up in a way that they stay as flat-surfaced as possible, for as long as possible, until finally rounding things off at the end, and avoid crossing over your flat-surfaced structure as you did here.

Looking at your earbud case, I did notice that the box you started out with did appear to be a little incorrect. As I've shown here, your lines seem to be pretty perfectly parallel to one another. That in itself is rather impressive, but given that we are definitely not looking at a box in one or two point perspective here, we should definitely be seeing at least a little convergence on those lines towards a shared vanishing point in order to convey enough foreshortening to be realistic. After all, shallow foreshortening is still some foreshortening, and to have none would imply that there was no distance between opposite sides of the box.

All in all, your work is still coming along well, so I'll go ahead and mark this lesson as complete. Keep up that patience and conscientiousness, as it will serve you well throughout the end of this course and beyond.
