250 Cylinder Challenge

Any feedback would be appreciated! Thanks :)
Taking an overall look at your submission, I'd say you did a good job. Your stand alone cylinders and cylinders in boxes for the most part follows the method for drawing cylinders very well.
The only thing of note I feel I should mention are the numbers 133, 135, and 134 on this page https://i.imgur.com/3ZyEPog.jpeg
As a cylinder goes further away, the ends will get closer, and in these examples you drew the shaded part in the opposite way.
Taking #133 as an example, without changing the lines at all, by implying the other end is facing us, the problem is fixed, although I am just showing this as an example. If we intend to draw this cylinder in a position where the right face is the face we can see, the lines should converge, even if ever so slightly to show that. I noticed this here and there in your submission, but as you went on your cylinders had this problem less and less but I figured I should mention it. With #133 that divergence is extremely tiny, but that tiny divergence still makes it incorrect. When a cylinder is in a shallow perspective like #133, just take extra care to make sure the lines do not diverge. Convergence, even just a little bit is correct.

another good example is this page here, where #89 is correct, while #91 is incorrect in the same way as #133, except here it is much more obvious. The way #91 is drawn here, implies that the cylinder widens the further back it goes, like a cone.

Other than that small nitpick, I'd say you adhered to the principles rather well. You made sure to make the farther end a little bit of a wider angle, and as you progressed, your cylinders became better and better, aside from that small nitpick. Just keep that convergence over divergence tidbit in mind going forward.
Thank you so much King Prawn for taking the time.
Looking at the examples you mentioned I can see now that I've drawn them incorrectly, the objects don't make sense from the viewer's perspective.
Appreciate the diagrams too, those were really helpful.
Thanks again King Prawn and good luck with your future projects!
When it comes to technical drawing, there's no one better than Scott Robertson. I regularly use this book as a reference when eyeballing my perspective just won't cut it anymore. Need to figure out exactly how to rotate an object in 3D space? How to project a shape in perspective? Look no further.
