Hello I'll be handling the critique for your lesson 6 homework

-Starting with your form intersections I can see that you've done a good job thinking about how these forms interact with one another, it seems that you can distinguish well when you need to use a curved line or a straight one. The only bit of critique I can offer here is that you don't really have to apply a lot of lineweight to the intersections as it may flatten the forms a little, and also don't forget to draw twice over any ellipse you freehand, plenty of your spheres are just drawn one time.

Objects

-Moving on to your objects you've done a good job trying to break them up into more simpler and manageable shapes, there are still plenty of things you can do to push them further.

There are are good deal of things to point out but I'll try to mention the most important ones only, but first let's try to explain what it is exactly that we are trying to learn during this lesson.

The main focus of this lesson is precision, this is something that we didn't worry about in previous lessons where we just focused on breaking each one of our subjects into its more primitive elements and we had to work with the outcome of our choices .For example we might have drawn the head of an animal too big, but that was not an issue as those mistakes didn’t take away from the things we learned by doing each lesson all the way to the end.

Precision and accuracy are two different things and in the context of this course accuracy refers to how close you were to executing the mark you intended to, but precision has nothing to do with drawing that mark, instead it is about the steps and decisions that we take beforehand to declare our intentions.

A good example of this would be the ghosting method, when going through the planning of a straight line we can place an initial and ending dot, this will increase the precision of our drawing by declaring what we want to do. Once that is in place we can draw the mark, it may nail those points, it may overshoot or undershoot, etc. The important thing is that prior to any of that we have used the ghosting method to think about each mark's purpose and how we are going to achieve it best rather than figuring everything as we go, this kind of approach is more useful for the kind of geometric forms that we are working with as they have different planes, sharp corners, and clearly defined proportions.

We can capture all of these elements through the use of subdivisions, these allow us to meaningfully study the proportions of our object by way of an orthographic study, after that is done we can apply those studies to the object in 3 dimensions. That way everything that we do is the result of careful planning, and nothing is done by eyeballing or improvising.

-Getting into some more concrete examples when it comes to your work, I think we can take a look at the calculator, you've drawn most of the buttons using guesswork and eyeballing rather than using the orthographic studies to decide where exactly to place them, all of this elements may seem trivial but when you get to the more complicated things like the cars and vehicles it is crucial that you try to identify every little element because in the end it all comes together to give that vehicle its character but it also gives you plenty of opportunities to tackle more complicated spatial problems that will help you to improve your spatial reasoning skills even more.

-One of those problems that is difficult to tackle is curved objects like the one you've drawn here https://i.imgur.com/D09kqqm.jpeg , it seems that you just freehanded a loose curve there.As explained here

https://drawabox.com/lesson/6/1/curves ,we can achieve a greater, more consistent solidity by first pinning down the specific nature of those curves by representing them as a chain of straight lines, or a chain of flat surfaces, then rounding them out towards the end.

Doing this also has the added advantage of giving us clear landmarks that we can identify and pinpoint in our orthographic studies.

On the few drawings where you've included orthographic studies I can see that you've just sort of laid down a grid and then drawn the object on top of it without really identifying where each landmark should be placed exactly, like the little square holes that are on the USB drive, so don't be afraid to push your studies even further to place each landmark at a exact point so that whenever you get to draw the object in perspective you don't have to guess at where each thing should be placed.

Okay that is about everything I wanted to cover, I'll go ahead and mark this as complete good luck on the next one
