congrats!

Now to the critique, Your linework is pretty good overall. Except for a little bit of wobbling here and there, and some slight arching. I would recommend to try to be more confident with your lines to fix your wobbly lines a little more. Also for the arching lines I would reccomend doing what uncomfortable said, which is to purposefully arch your lines in the opposite direction. Also arching lines tend to happen when you aren't fully using your shoulder pivot. Of course this is something you would get over time, so for now just try and get your lines to be more confident.

Next is your ellipes, for the majority of them I saw that they were clean and confident so good job. Once in a while I saw a circle or two that they looked like you were trying to make them fit into the grid tables especially the ellipses in which you had to fit them into the squares. Overall you did a good job with your ellipses, its just something to keep in mind, cause we can sometimes forget.

Your lines also for the persepctive grid using one point perspective is also good. I just wanna say that the lines should either perpendicular or parrel to the horizon. Just something to keep in mind. i just saw your lines were still a little arched, so they weren't parrel sometimes. Of course that comes with practice so keep up the work and you should get better.

In the organic perspective and rotated boxes is also good. I did notice that it was kinda hard to tell if you plotted your points before ghosting your lines. It might be the ink covering it, so nothing to worry too much. Overall very good. I would also recomend drawing the lines that go inside your boxes to better your understanding of 3d boxes, but thats something you will get plenty of practice in the 250 box challenge.

Overall very good. Just some things to remember. Don't forget to plot your points before anything. Don't forget to ghost your lines. Good luck and I hope you continue to grow as an aspiring artist. Level up up to 9,000!!!!!!!!!!!!!!!
