Hey, good job!

First of all, the purpose of Organic perspective is to: "...throw you into the deep end of the pool without having yet taught you to swim". So don't worry too much if you feel it's confusing.

I know it's fine to use a ballpoint pen starting out, but I really do recommend using fine liner/felt tip. It makes a difference. And it makes a difference in how much you'll learn and be able to take away from these lessons. So not using the recommended materials can be considered a bit of a waste of your own time.

Lines

The superimposed lines are looking good. Only fraying on one end, accuracy will get better over time. What worries me are the ghosted lines where your lines are missing the plotted points on both ends. make sure you take the time to properly line up your starting point for the ghosting motion (this goes double for the ghosted planes where you're over-shooting quite a bit). Your ghosted lines feel like they were drawn with confidence (which is very good!) but have some arching problems. Try to make sure you are drawing using your shoulder pivot.

Ellipses

Not many problems here, they fit quite snugly and seem to be drawn with confidence. It's a bit hard to tell, but to me some of them seem to be drawn trough too many times - should be 2 to 3 times, (2 times preferably) - but I may be wrong! There are some misalignment issues on the funnels, but that seems to get better on the second one. Good job!

Boxes

On Plotted perspective the height lines should be perpendicular to the horizon line, since these vanishing points are at infinity. If you were trying to make boxes that weren't sitting on the ground plane look at these notes on the difference of horizon line, eye line and axis: https://drawabox.com/lesson/1/7/lines

Problem with the hatching on the Rough perspective - it's sloppy and diminishes the feeling of 3d. As soon as we pass the vanishing point (going left to right) the hatching is on a side of the boxes that is not visible to us. Hatching: do it neatly or not at all.

For the Rotated boxes you seem to be going over lines multiple times, don't. (This also goes for the Organic perspective). If you mess up a line: keep it as if it was correct. If you're trying to add line weight, do it in 1 - 2 passes. The hatching is a bit much and makes it hard to see the construction lines sometimes. The front facing planes of these boxes are looking quite good, so good job! They problems arise in the back planes. They don't rotate and they don't follow the direction of the front side of the box, which breaks the illusion of rotating boxes. This will get better after 250 boxes :)

Generally good job with the Organic perspective. Some of the boxes are skewed or not converging properly (sometimes diverging even) but that's fine. They diminish as the go back in space and you did the exercise.

Sorry if i'm not being clear or sound too harsh! If there's anything that's unclear please ask me to specify!

All the best.

Overall your work look pretty legit to me the only promblem i see is line weight dont forget about it.Not really that big promblem because you will adapt to it over time but in conclusion nice job.
