So far my day's been pretty long with loads of critiques, and Lesson 7 is always one of those that I'm afraid to touch, and yet am almost always pleasantly surprised by what is essentially the culmination of all the hard work the student has put in. This is no exception, not even a little bit. I'm extremely pleased by your work here.

Starting with your form intersections, I actually went back and looked at your Lesson 2 work, and while your work there was fairly solid for what the expectations were, the difference is night and day when you focus on the confidence behind your linework and behind the construction of the forms, and the self-assuredness with which you've drawn the actual intersections. The intersections are mostly correct, though I noticed down a couple corrections here (along with one I legitimately have no idea how to solve).

Jumping down to your vehicle constructions, I honestly don't have any actual complaints - or at least, very few, and none of significant note. Each one is extremely solid and constructed with a level of precision and confidence that is hard to compete with. While you clearly didn't dig into any significant detail, what you did capture was all the important stuff, and without detail to hide behind, your grasp of form, spatial relationships and construction as a whole is laid bare for all to see.

One minor point I noticed was with the tank towards the beginning - while I can't be certain without looking at your reference, the overall proportions here don't really resemble any tank I'm familiar with, specifically with the treads/drivetrain section feeling rather squat and short. Doing a proportional study off to the side, looking at the various orthographic views of your vehicle and breaking them down into a unit grid can definitely help with this. That said, despite the apparent disproportion, the construction stands for itself, and while a little extra line weight to help key edges of the silhouette stand out would have been nice, it feels like what you've drawn is something real and physical, if a little unfinished.

To that end, I really did like the use of solid blacks in your various trucks and the car at the end to separate and clarify your resulting drawing. Where it didn't work quite as effectively was in this fokker plane, where it read more as you attempting to capture a highly simplified form of form shading along the underbelly. While the rules are a bit relaxed here, using solid black to separate out the various layers of an object (interior vs. exterior) is generally okay, but don't use it to separate different faces, as this actually works to somewhat flatten out the result as shown in this simplified example of two boxes.

In that regard, the use of solid black on the interior of your triumph spitfire car at the end worked out really well, but the same along the circumference of the wheels didn't work quite as effectively, instead making the side plane of the wheels appear more graphic and flat.

The last thing I want to mention comes down not exactly to detail - it's fine not to delve into detail, and I don't really have any issue with where you decided to stop your drawings here - but more about what constitutes detail, and what constitutes construction. The line in some cases can be blurry, but looking at something like this jeep, I'd argue that there was a lot more solid, constructed form to be pursued in its front area - building out some headlights, grill, bumper, or whatever else applies. These are all still things we'd create out of solid form, rather than using textural techniques (cast shadows) to achieve, so in this regard one could argue that your drawings stopped a bit short of "complete".

Again - I'm not too bothered by it, as far as the main focus of this course goes, but it is something to keep in mind.

So! All in all your work here is solid and I am confident that when it comes to the major concepts explored throughout this course, you've improved a great deal. I'll happily go ahead and mark this lesson as complete. Congratulations on completing the Drawabox course.
