Hi, good job for completing lesson 1 ! Let's dive into the three sections of this lesson !

Lines - Be sure to use a fineliner all the time ! Ballpoint pen tend to fade and it's more difficult to see mistakes ! For the superimposed lines, the lines seems to fray too much sometimes, be mindful of that. Draw your lines firmly and thoughtfully. For the ghosted lines, well done, they don't arc, they are drawn confidently.

Ellipses - Be careful, on the ellipse tables, your ellipses should touch the top and bottom of the boundaries, and should be tightly packed together. Also, some are a little wobbly, and keep in mind that you should draw through them 3 times at most, 2 times being the best. For the funnel exercise, your ellipses are well aligned with the axis, good job !

Boxes - This was the tough part. The rough perspective is looking good, but be mindful of keeping your horizontal lines parallel to the horizon and verticals perpendicular. The rotated boxes seems to be well drawn, but your hatching is distracting and is hiding your linework. Try to have a nice, tight hatching, by ghosting your lines. In addition, you should reinforce the lines of the boxes that are visible to us (in contrast of the lines that are drawn through them), in order to make the boxes pop more. You can see all of this in the example of the lesson :

Also, your boxes don't rotate correctly on some extreme corners. But keep in mind that it's a difficult exercise, and it's totally normal to make mistakes at this point.

For the organic perspective, it's not very clear, and I would advise you to add lineweight to the part of lines that overlap (in order to know which box is in front and which is behind). Moreover, to convey a better sense of depth, I would advise you to draw more heavily the boxes near us, and in a lighter way the boxes far away. Like the line used to establish the boxes :

Be aware that I'm mostly highlighting your mistakes, but it's overall a good job. And even there are mistakes, you managed to go through the whole lesson.
