Hello friend, in the part of superimposed lines it feels a reliable and smooth line so that's fine, in ghosted lines it seems that before touching the end point you curved the line to touch the point and here it is better to keep the line straight even though it crosses the point , in the ellipses table try to maintain smoothness and confidence before precision few times your lines felt shaky so it's fine and in rough perspective a few horizontal lines are slanted, make sure to keep them horizontal

Regarding self-criticism, it is good to consider them but while doing your exercises concentrate on them and once you finish you can write them down in another notebook or a part of the sheet where it does not interfere with the exercise.
