superimposed lines : i can't find a point that you are trying to hit, but you should. Try as possible to hit a single point with all 8 lines, that's the aim of the exercise to build your muscle memory.
ghosted lines & planes : missing the final point is okay at first, but gabs in the middle of your mark is a sign of hesitation which you don't want to have. Commit to your line once the pen hits the paper and after making a complete mark see where you need to improve.
Ellipses (all exercises) : they are good but try to not repeat more then 3 times.
plotted perspective : nothing to say
rough perspective : using the ghosting method will improve your work, definitely.
rotated boxes : your beginning looks very promising but not completing is a sin.
organic perspective : actually i liked it to the point of saying that it is far from lines exercises.
Next Steps:
you should repeat lines exercises with more confidence, focusing more on hitting the same point in superimposed lines.
complete the rotated boxes, feel free to rewatch the exercise video as many times as you need.
