Whew! Okay, let's get started.

Your form intersections are, remarkably, fantastically done. The linework is ridiculously confident, your forms feel cohesive and solid, and the way in which you've welded them all together reinforces the illusion that they all exist within a real, three dimensional world. Thinking about to the resistance you had to this exercise ages ago, it certainly is remarkable how far you've come along.

Your cylinders in boxes are similarly well done - there's one or two lines that fly off on their own but they're more outliers - most of them stay within a fairly respectable margin of error when it comes to alignment with the vanishing points of the container box.

With those out of the way, let's move onto your vehicle constructions. Amusingly enough, your coast guard boat demo drawing came out extremely squat, with the primary issue being more related to the width of the boat (which hadn't been accounted for in the visible proportion studies). That said, despite this glaring oversight, the result still looked entirely believable and real, if a touch toy-like. Still felt solid and real though. Pushing the foreshortening a little harder would have probably helped with the toy-like scale as well. We can see the difference between such shallow foreshortening there, and the electric bus drawing that follows - despite the boat clearly being way bigger, the bus ended up looking exaggeratedly large due to the more rapid convergences.

For this one, one thing that jumped out at me rather quickly was the lack of spacing between the treads and the main body beside it. Keeping things quite as tight as that can impede the impression that the vehicle itself can actually move without getting hung up on itself. Additionally, always remember the basic principles of perspective - that tread's foreshortening is super dramatic. As a whole, I think you jumped into the detail too soon on this and didn't block it in simply enough ahead of time. It can be pretty easy to use the subdivisions laid out already as landmarks and just jump into more specific layers of construction - and before long you will totally be able to do that. But for now, building the basic geometric forms first is an important step to take.

We can see you doing this a little more with the.. weird lamborghini pickup truck, which.. honestly upsets me more than I'd like to admit. Not the drawing, that is largely well done and blocked in quite nicely, though the alignmment of the back cylinders diverge a touch from the front wheels, so keep an eye on that.

I quite liked your camaro drawing - again, the proportions were a bit squat, but your grasp of spatial reasoning and construction are by and large well developed enough to ensure that the resulting object was believable and solid, and you even captured a good deal of its character.

Of all your drawings - at least the car ones specifically - I think the smart car is the best of the lot. I can see you relying more and more on freehanding your lines (apparently frustrated with your ruler), and that does result in some imprecision with your lines, but here it still all comes out feeling solid and true. The same cannot be said about the weird stubby little plane that follows, but hey - I can only imagine you thought your ruler was a boomerang, and were stricken with grief that it did not return when you threw it into the outback.

Leaning heavily into freehanding isn't doing you a whole lot of favours when it comes to cars - the station wagon feels more like an old jalopy, or maybe like a sagging pair of pants being worn by a series of soggy cardboard boxes, but the correct decisionmaking (aside from giving your ruler to a flock of wild kangaroo) is all there. Just remember - if you're going to freehand things, the ghosting method is always going to be the king here. Don't go back over your marks, don't "sketch" so roughly. The ghosting method exists purely to allow you to execute your marks with confidence, without hesitation or fear of making a mistake. With that confidence, should come the willingness to accept whatever results, and not to try and hedge your bet and go back over it. Don't show weakness.

Your microjet is another big success. Yeah, the wings are misaligned, and the far one is definitely positioned in such a way that it connects to the body of the jet further back (be sure to draw through such forms in their entirety so you can understand how they all relate to one another). Still, I'm very happy with how solidly the forms do in fact connect to one another. Also, when it comes to figuring out how far wings should extend, the only trick I know for doing this is one I truly hate, specifically because it means looking at the reference as it exists in 2D space. You basically take the tip of the wing and draw a line across it (or eyeball it) to see what else is at the same "height" in the image, as shown here. You can also do the same working vertically instead of horizontally. Knowing how to use a straight edge can certainly help with this, though.

Lastly, your train at the end came out really nicely too. Not a complicated object to draw, given that it's really just a glorified box, but you handled the subdivision very well, and did a great job of shearing the angle across the front of the container box to properly lay out the front face of the train. All in all, very well done without much to complain about.

So! I think I'm overall pretty pleased with your work here. I think you could certainly get a lot more work in with the cars to increase your comfort, I think you made a lot of progress with them and have certainly stepped up from your initial "i don't want to draw cars, lessons 6 and 7 are useless to me, i only care about fuzzy critters".

With that, I'm going to go ahead and mark this lesson as complete. Congratulations on reaching your coveted greenie status, and I hope you continue improving as you've done so over the course of the last couple years.
