linework:
Your lines are long and confident however something notice throughout your linework in general is are some bends and curves around the second half/ ends of the lines. IT seems like you are making marks and then halfway through drawing you realize you are going to miss your mark and make a correction. When lines we should prioritize confidence and straightness over accuracy. When drawing lines ghost the motion repeatedly and when tou feel ready to make the mark for real focus on the sensation you have been building up. Addtionally when making liness don't be afraid to place points multiple if necessary to give you a better sense of direction and aiming.
Planes the issue with your planes mainly stems from your linework. You also have some issues with finding the center point the non corner lines are very off line. When drawing the center lines their is no magic trick but you must make sure they pass throgh the point of intersection between the ellipses. I think what should do is place points on the sides of the planes that have the center point between them.This issue also affects your ellipses. The center of your ellipses should be be at the point of intersection between the corner lines. And the the minor and and major axis of the ellipse are basically the the T formed from the center lines all you have to do is connect them.
Ellipses:
Your ellipses in general are ok you are drawing them multiple times. the only issue I would say is moter control which only comes with more practice and ghosting.
However the tunnel ellipses have a couple problems. First when seem to be having problems with your center line so just to understand you can make the tunnel first and then add the line inbetween. Also rembember what I said eariler about using points to help guide you. I think the crux of the problem is that you are attempting to place to many ellipese in between them The point of the intersection is for them to gradually shrink and then grow back to their original size at the end of the tunnel. addtionally You have a tendency to tilt your ellipses when doing this your eplipses minor axis should be parrallel to the center line you drew. Ideally it should be the minor axis which is it's point.
Boxes and perspective.
Your boxes and persepctive in general really need some work. Do note Im not trying to be harsh or mean, but your are fundementally constructing those boxes incorrectly. You should reveiw the concept of a vanishing point. You seem to have intreprested that points making the corners of the box should converge with the vanishing points. You are wrong. The lines between the corners(the edges) converge towards the vanishing point. This is espeacially true with your plotted perspective(the one where you used the ruler. Some of the sides of the boxes are also wrong. When making box you are technially making a collection of planes. And some of your planes are squares they are triangles like bottom of the center box in your organic perspective in the bottom attempt is the best example of this. Thier is a specific technique you will learn later on in the 250 box challenge called the Y method.
All in all this was a decent attempt good job move on to the 250 box challenge
