Hey there Cheerful, congrats on finsihing lesson 1. Let's get right to the critique.

Starting with your super imposed lines, you are doing a pretty good job keeping your confidence and executing with your shoulder. You do have some substantial fraying at the ends, which isn't a huge deal right now, just keep practicing these in your warm ups to find a good pace to get those groupings tighter. Your ghosted lines are showing some wobbling and unsteadiness indicating you are trying to steer your pen instead of ghosting and executing a confident swift stroke with your shoulder.

Moving on to your ellipses, the overall shapes of them are good - they are smooth, confidently drawn, and have no points or fflat regions on them. Your ellipses in the tables exercise are packed tightly together to leave no room for ambiguity and you have a good variation in size and orientations. Your ellipses in planes are getting a little sloppy with your follow up passes while drawing through so keep practicing to tighten those up, but they are making good contact with the plane edges to make sure they sit snugly in the bounds of the planes with no room to float around. You're doing a good job keeping your ellipses within the funnels and your minor axes are for the most part aligned with the funnel axes. The one exception is the bottom left set of triangular funnel - the ellipses there are pretty skewed away from the center axes.

With your rough perspective boxes your lines are starting to get a bit more confident. Your horizontal lines are parallel to the horizon and verticals are perpendicular resulting in properly oriented boxes. Your converging lines are right on track and your extension lines are applied correctly. The accuracy at this point isn't a problem and accuracy of lines to far away points will improve with mileage. Just keep practicing ghosting and using your shoulder to get those lines smoother.

Now let's look at your rotated boxes. Your lines are getting even more confident so that's great to see. You did a good job pushing this to completion and exposing yourself to new types of spatial puzzles and solution methods, which is our only goal for students. In terms of the mechanics of this exercise there are a few things to point out. You are not rotating your boxes, but instead skewing and shifting them. Give this gif some more watches and focus on how the motion of the vanishing points drives the rotation. Additionally your boxes are pretty far apart and if you keep them packed tighter together you can use adjacent lines as perspective guides. Overall though, good job pushing through and keeping things neat.

Finally let's look at your organic perspective. Your boxes are nice, albeit a bit shaky in the line work still. Your compositions have good explorations of space and a good spread of scales to give a distinct foreground midground and background. To further push the illusion of three dimensional space you could have your forms overlap more to make them feel like they exist in the same space. Your perspective is off to a good start and you are paying attention to the convergences of your lines. Overall this is a good start.
