Okay, These are both looking a lot better. Your rough perspective exercises turned out well. It's great that you are keeping up with the confident linework on these. You are also doing a good job extending the lines back on your boxes to check your work. As you can see some of your perspective estimations were quite off but that will become more intuitive with practice. One thing that can help you a bit when doing a one point perspective exercise like this is to realize that all of your horizontal lines should be parallel to the horizon line and all of your verticals should be perpendicular(straight up and down in this case) to the horizon line. This will help you avoid some of the slanting lines you have in your constructions.

These were both huge improvements and I think you are understanding most of the concepts in lesson one quite well. I'm going to mark this as complete and you can move on to the 250 box challenge. Good luck!
