Hi there! You're making progress but sometimes you still make your lines a bit wobbly, so to make sure that you know how to draw confidently I want you to draw one organic perspective box, and take one photo after every single line you draw. After drawing each line note at the side which level that line is. Keep in mind that all lines that are wobbly (not straight) no matter how accurate they will be a level 0 Top line here is a level 1 line and bottom is a level 0 one, as an example.

I also think you might be rushing a little bit at times. Make sure you take as much time as you need to do your best on every line you draw. You haven't drawn starting and ending dots on some boxes as well, so make sure you always do it as it's extremely important for the ghosted lines exercise.

And last thing, your lineweight lines are a bit wobbly as well, superimposed lines as lineweight should be confident as well.

Good luck and keep it up!
