Hey there Fuyuki, good job finishing lesson 1. No worries with the fineliner issue as you are allowed to work lesson 1 and the 250 box challenge with a pen as well. Without further ado let's take a look at your work!

Starting with your super imposed lines you are drawing them pretty confidently for the most part. All of your starting points are at the same spot so you are taking your time in starting your lines and executing confidently. You have a little bit of wobbling in your lines here and there, but that is the exception to the otherwise consistent lines you are producing. With your ghosted lines you are doing a good job driving the motion from the shoulder and drawing confidently. There are a few hiccups here and there, but that's totally normal and you're off to a great start.

With your ellipses in planes you are drawing them confidently so that's great. Your drawing through is a little spread out so just keep practicing using your shoulder and getting control better. You are doing pretty well at hitting the points on the planes you need to so that they remain within the bounds snugly, but with your tables exercises there is more room for ambiguity as the ellipses aren't packed in tightly. As for your funnels, really nice keeping them all aligned with the minor axis. That will be important for later lessons with organic forms.

Now looking at your rough perspective, your lines here are improving a lot more! They are planned and confidently executed. Your vertical lines are perpendicular to the horizon and your horizontal lines are parallel to it, resulting in correctly oriented boxes. Your converging lines are on right right track (although there as some hit or miss), as indicated by your correctly applied check lines, nonetheless good job there. Your accuracy will improve with practice so keep it up! =).

Good job on completing this exercise. You did a good job on it, but more importantly you completed it so you could be exposed to new types of spatial problems and solution methods which really is our only goal here for students. In terms of the mechanics of the exercise there are some things you could improve upon. Firstly, your boxes are pretty far apart. If you keep them closer together you can leverage adjacent lines to use as perspective aides. Additionally, you weren't rotating your boxes too much, so watch this gif again and pay attention to how the rotation is driven by the vanishing points moving along the horizon line. Overall though you did a good job here and you should be proud!

Finally let's take a look at your organic perspective exercise. You are doing a good job selling the illusion of depth here. Your boxes get smaller and appear to recede into the background and your larger ones up front serve as a good starting point to set the scale. You overlap your forms which further reinforces the illusion and you've done an overall a solid job. I would have liked to see a few more boxes in some of these for more mileage, but that's ok. Your perspective is on the right track. Often times your lines aren't converging at all, which isn't correct, but that's nothing some boxes won't cure...
