Hi there weijak! Overall you've done a pretty good job over the challenge, I'll try to mention the things I catched so you can keep improving, let's go!
On the first part you're doing a pretty good job with the cylinders, they're confident and you're applying the ghosting method properly, I can also see you understand that the ellipses on the farther end will be smaller and that they will have a wider degree.
A thing I think you might not know is that this degree of foreshortening depends on how small the ellipse is. So if a cylinder gets foreshortened a lot and the farther end is pretty small, the degrees of the ellipse would increase too.
You're applying the checking method of the minor axis properly so nothing to comment on that!
In the second part you're doing a pretty good job too, already on the start of it you were eyeballing squares pretty nicely, and the convergences are good as well, you're also applying the correction method correctly on all of them.
The thing that caught my eye the most is that you have a tendency to get the minor axis on the ellipses a bit off, so I think there's something that might throwing you off. I recommend you from now on to mark the major axis with dots before drawing any ellipse, that should help fix this issue.
The second thing I wanted to comment on is that your boxes have improved a lot, I can see that by the end of the challenge you're way more aware of the relationships between lines. But one thing I want to comment on that you might not be thinking about when drawing boxes, is that you can use the angle relationships and positions between lines to make more accurate guesses. Take a look at this, hopefully it makes it a bit more clear.
This is also related to this diagram, not sure if you have seen it before, but take another look at it anyways, you might discover something new.
Overall like I said you've made great progress, so I think you're ready to go on to lesson 6! I also recommend you to start giving a shot to the adittional boxes exercises on your warmups, specially the boxes on strings, I think you're more than ready for them!
