Heyho,

first: congratulations on drawing the 250 boxes

All in all your lines seems pretty confident, although there are some mistakes here and there. In most cases its just some overshooting, what isn’t such a problem. But I also saw some wobbly lines and some that bend. Keep that in mind when you go forward and concentrate on doing straight confident lines, while using your shoulder.

I see a proper improvement of your line convergence after box 85+, that continues until the end.

What is a bit sad is, that you barely draw boxes with strong foreshortening (https://drawabox.com/lesson/250boxes/1/foreshortening) and very different scale (e.g. two very long and one very short axis, or two very shot axes and one very long). In my opinion such boxes help to get a better understanding of the line convergence and how lines interact. I would recommend drawing one, maybe 2 of such boxes as a warm up when you go forward with lesson 2.

All in all seems pretty decent. So have fun with the next lesson :D
