Just to start, I won't be including your warmup sketches in this critique. Aside from already providing an ample body of work here in the lesson itself for me to assess your understanding of concepts, critiquing work that does not purposely adhere to all the principles of the course would go well beyond what these critiques are intended to be.

So, let's jump right in. Looking throughout the set, I'm seeing vehicle drawings that fall into two distinct categories. There are some that demonstrate a strong overall grasp of constructional principles - of pushing the subdivision of your structure to find more precise positions for various features and elements. These include many of your non-car vehicle drawings (planes, tanks, etc). Then there are the drawings that lean much harder on observation rather than construction, on creating an accurate image on the page, rather than exploring the steps necessary to actually construct that object in a manner that is more meaningful as an exercise. I will of course touch upon both.

So, with that first category, you've got some really impressive drawings. You delved into considerable complexity with your structure for this plane, and I'm especially pleased with how you approached the propellers (although I think the propellers ended up being quite a bit shorter than they ought to have been). The overall structure is quite solid, though you did break some rules in adding shading and hatching to aspects of your drawing. As you may recall, back in lesson 2 I specifically talk about how form shading should not be included in the drawings for this course.

Another drawing that came out very nicely, structurally speaking, was the locomotive. You built it off a very strong core of major forms, and didn't stray from the kind of solid structure to add any detail that was not supported by the scaffolding that was already in place. That is in many ways in the nature of a locomotive, which is what makes it such an excellent subject to study. All the same, you pulled it off quite well.

Now, jumping ahead to your cars, and your motorbikes, we start to get into the territory of you skipping over pretty significant steps of construction to draw things more by eye, rather than applying the principles of construction. You certainly start well enough, laying down the techniques for constructing to scale, but you do so mainly to build out the appropriate enclosing box, and then take significant liberties based on what you see in your reference image. You take big leaps to put down what you see, rather than finding your way there through constructional means.

This suggests to me that at least when it comes to car, you're forgetting what Drawabox is all about. That the drawings you do in this course are not to draw a pretty drawing, and not to capture the likeness of your reference by any means possible. Each and every drawing here is an exercise, one that develops our spatial reasoning skills by forcing us to think about how the forms all fit together, how they build upon one another, and how one can work in 3D space. You do a great job of this in many of your other drawings, but your cars are not among them.

Now obviously the cars you included in this set are far less sketchy than those you do for your daily studies, but I suspect that your familiarity with them for the purposes of those warmups is what caused you to go off track here. You forgot about what was being asked of you, and fell back to what you found comfortable and familiar. It's entirely understandable, but it is of course my job to give you a little shake and to remind you to follow the instructions of the course to the letter, and to apply the methodologies shown in the demonstrations.

You did after all follow along with the shelby mustang demo, to a point - but you definitely put the linework down with a hesitant hand, purposely leaving contour lines broken in areas like this instead of drawing all of your lines with confidence. Still, you did a decent job of following along with the demo, and so you should have been able to apply the same principles in drawings such as this.

There were some car drawings that were better structured, and I should certainly give you credit for that. This one for instance relied on much more underlying structure than the others, and it came out much stronger for it. I'd have been entirely satisfied had you applied the same principles to your other cars.

So, I'm going to assign some revisions below and allow you to apply those principles now. Remember - you are not just being asked to draw some cars. You're being asked to build up to them, using constructional principles. I know you can do a great job at this - you have strong observational skills, as you've shown thus far. You also have strong constructional skills, as you've shown with the other vehicle drawings. You merely need to combine them.
