So I actually forgot to post this up for critique and as of the time I'm posting this I've just finished lesson 2 as well. I thought this was a really good exercise and I learned a ton from it. Originally I only wanted to spend about two weeks on this and end early even if I hadn't finished by the deadline. But after talking it out in the discord server I decided to go for another week and I ended up with 220-230ish boxes.

The things I really struggled with even towards the end was: 1. line confidence 2. that the last corners lines behind the box doesn't fit with the rest of the lines.

I'd appreciate any feedback of course but especially regarding those two subjects. But with line confidense especially I suspect the only real solution is to practise and try to stay conscious of it.

I think I got better with the last corner by the end because I started planning out how that corner would best fit by adjusting the second last corner accordingly (it's hard to explain through text). I also started keeping track of how many lines on each side were sufficently close to a shared focal point (which is what the "x/4" thing is) by the end.
