Hi. I'd like to review your lesson and give you some feedback. Overall looks good, but there are some points I want to mention. First, your superimposed lines have a lot of fraying throughout the line. It is a little too much in my opinon but something that should improve with time. I would suggest doing them as a warmup for a while as you go throughout the lessons. Doing this has definitely helped me.

Your elipses and ghosted lines look really good as do your planes. Your plotted perspective and rough perspective pages are also good, with the exception of where it appears you tried to make the lines thicker as you said and it created double lines. I think this will improve with time if you add some exercises as a warm up though. However, good job on those.

For the organic perspective pages, some of the boxes have very dramatic foreshortening which you should try to avoid on this exercise. Also your lines are extending a bit past each corner. I'm not sure if you did this, but I would suggest planing out each line by placing a point and then ghosting the line a few times before laying down the final line. That should help with getting the shape right and not overshooting the corners. I'd really like to see one more page of organic perspective with some improvements though.
