Hello Delufra, congratulation on completing Lesson 1. Here are my thoughts,

ghosted lines: at times there is arching. As long as you are drawing with your shoulder this is acceptable and will get better at it with practice. You can also choose to arc slightly in the opposite direction to counter that effect. There is a bit of wobble too, just remember to keep executing your strokes fast and with confidence.

ghosted planes: occasionally the cross sections will be off-center, just remember to give it a bit of thought before placing those marks down.

table of ellipses: remember to go over your ellipses multiple times (2-3) and try to keep them as tight as possible. Most of the time you are getting it right, but occasionally there will be one or two attempts that are the exception.

rough perspective: most lines are correct however a slight wobble can be perceived.

organic perspective: you seem to have struggled a bit with this exercise. Remember that your boxes should be growing at a consistent rate as the get closer to the viewer. Keep your strokes smooth and confident, even if you miss your intended target.

notes:

at times you'll go over lines in an attempt to correct them, don't. Just move on as if it had turned out as intended.

Conclusion:

Overall, you seem to have grasped the concepts of the lesson and I will gladly mark this submission as complete. Just remember to incorporate this exercises as warm ups for subsequent lessons. Good luck on the 250 Box Challenge.

Best of luck moving forward
