Nice work overall. You're doing great work with your lines section - maintaining smooth, confident strokes with consistent trajectories, and reinforcing them with control by using the ghosting method effectively. Your ellipses are generally in the same vein, with clear focus on keeping them evenly shaped, but still managing to achieve a good deal of accuracy. Jumping further down, your rotated boxes show that you're taking care to follow the instructions to the letter.

I noticed that while your rotated boxes came out really nicely, there is room for improvement in keeping the gaps between your boxes more consistent and narrow, as this allows us to eliminate any guesswork from the equation, instead following along neighbouring edges wherever possible. Your organic perspective boxes also a good start, though as is expected for all students at this stage, there's plenty of room for improvement when it comes to getting your lines to converge more consistently towards their vanishing points.
