Starting with your form intersections, the intersections themselves demonstrate a very well developing understanding of how these different forms relate to one another in space. While at this stage it's normal for students to be well familiarized with intersections between different flat surfaces, and to have some confidence with intersections involving a combination of flat and curved surfaces, it's still common for them to struggle with those intersections between multiple rounded surfaces. You are definitely showing more progress here than most, although there is still some continued room for growth, as shown here. The key comes down to identifying which way a surface curves and in which direction, and then using that information to help inform how you stitch together the intersection line overall. This diagram helps to illustrate this concept.

The other point in regards to your form intersections I wanted to mention is that while the intersections themselves are generally good, the way in which you're executing the lines themselves could use some work. Don't go back over them so aggressively, and as with all of your freehanded marks, be sure to apply the ghosting method so as to achieve a smooth, confident stroke. Additionally, note the use of line weight explained here - it's not really about going back over the areas you want to stand out, but rather using them to clarify how different forms overlap where those lines cross on the page.

Continuing onto your object constructions, your work here was similarly well done. I'm especially pleased with constructions like your power plug, your lighter, your coffee maker - really the majority of the constructions where you really held strongly to the idea of maintaining very tight, specific relationships between the phases of construction. The areas where those relationships were somewhat looser also wasn't your fault - they were mainly the computer mouse constructions, which both faithfully followed the way in which the orthographic plans were demonstrated in my own computer mouse demonstration.

To that point, I do want to point you to these notes which were added only last week, so I expect you may not have had a chance to see them yet. The short of it is that as I've been critiquing homework for this lesson, I've been putting more and more emphasis on how those orthographic plans can be used. This information will eventually be incorporated into the demo material (although it'll be a while, as we're basically doing that for the whole course), so in the meantime those notes explain how to leverage those techniques best.

Based on how you're approaching those other constructions, and how meticulously you're maintaining tight relationships between each step, I think this more advanced use of orthographic plans should feel right at home, and you'll be able to leverage them further when you get to Lesson 7.

There's really only one other thing I wanted to call out - for your coffee mug on this page, I think that would have been an excellent opportunity to leverage the approach explained here in regards to tackling curving structures. The gist of it is that curves are inherently vague, and when used as the basis of a construction can result in that construction feeling less solid. Instead, we can build up those structures using chains of straight edges, or flat surfaces, building it out in this manner and only rounding things out towards the end of the process. That section includes a demonstration at the bottom which demonstrates how you might approach this for a coffee mug, so you can check it out and see how it differs from your own approach.

And with that, I'll go ahead and mark this lesson as complete. Keep up the good work.
