250 Cylinder Challenge

I apologize on how some of my ellipses turned out. Despite doing them for a long time, I'm still really terrible at it.

Hey Wifu, lets go over your work!
Starting out by your cylinders around an arbitrary axis, I have to start by saying that they are looking pretty good. You are overall doing a good job on keeping them solid and you experimented quite much with different foreshortenings, rotations and sizes. Regarding what you said about ellipses, dont worry, you have probably come to realize that they are tough even when we put a lot of practice into them, just keep at them while focusing on confidence and dont let those rounded a-holes get into your head.
Now, although you did an awesome job, there is something I want to talk about for two reasons: 1. I want to at least pretend that I taught you something in this critique, and 2. I have a suspiscion that you are applying this principle on a more intuitive level (which is great) and I want you to be conscious about it, since that will give you more freedom while doing it!
This principle I want to touch on is mainly about how foreshortening manifests itself in our cylinders (and other objects of course), this happens in two "shifts". On one way, as a cylinder goes into 3d space, its ellipses suffer a "shift" in scale, where the closer ellipses will have a bigger scale than the further one, on top of this, when the shift in scale is more drastic, we are being communicated that the foreshortening is also more drastic. On the other side, when cylinders move through space, we know that there is another shift on the degrees of the ellipses, where the further ellipse has a wider degree than the closer one, and as the other case, if the change in degree is more drastic, we know that the object is being really foreshortened.
Up to now, Im sure that you know all this stuff, but where I want to put my emphasis is that this two shifts need to work together so they can communicate the same kind of foreshortening to the viewer. As I said, you did a good job on this lesson, so I nitpicked this two cylinders so I could make a point on what Im trying to explain. As you can see on the first one, you are making the back ellipse just a little smaller than the closer one, and although there is the lentgth factor to take into account, you are then making a really drastic change on the degree of the back ellipse. I know its a small change the one I did, but I wanted to use it as an example to explain all this, instead of just drawing on top of it without explanation. Now, I added the second one to show that sometimes the one being wrong can also be the closer one, it all depends on the process.
Now, moving on to your cylinders in boxes, If Im being honest, I dont know if I have something to add about what you did. You did a great work here, you may have started to realized that this section of the challenge is not so much to test your cylinders, but to test your ability to create boxes with more squarer proportions that are able to fit circles in 3d spaces (or ellipses as we call them). You did good on those boxes and I can see that because you cylinders are showing that, I still think that number 249 is pretty funny, but its clearly just a hiccup.
Im going to go ahead and mark this challenge as completed! Keep up the good work.
Next Steps:
Feel free to move on to lesson 6
Hi weijak, thanks for the critique! Yeah, the first set of cylinders were alot about thinking about them on an intuitive level. I went about them from a trial and error standpoint, resulting in some of them looking rather silly but I learned alot in this lesson. Thanks again!
Well im glad I was able to explain how they worked! Good luck moving forward.
Drawabox isn't the be-all, end-all of drawing fundamental education. Our approach prioritizes certain concepts over others, and while we believe it do so for good reasons, ultimately it doesn't appeal to everyone. If Drawabox simply doesn't work for you, give Proko's Drawing Basics course a try - at the very least, you'll probably find it to be a hell of a lot more fun.
