Hey! I'll divide up my critique into three parts, firstly the superimposed lines, then the ghosted lines, then the ghosted planes

1) The superimposed lines are good, you have a consistant starting point for them, and though there is fraying (that's natural at the beginning don't worry) they're fairly smooth and there isn't much arching!

2) I see a bit of bowing/arching in some of the ghosted lines, and there seems to be a bit of wobble, this seeps into your ghosted planes as I will explain in the next point and give a lil advice, but other than that you're quite accurate. You're hitting the points the majority of the time and you're not too wobbly or whatnot

3) Your ghosted planes are very accurate, however I think it's because of a "non-ideal" reason, which is that I suspect you're taking the ghosted planes too slowly, because I can see wobble in a lot of the lines, I could be wrong about this, it can also be affected if you're not drawing on a flat or smooth surface. Smoothness is always prioritised over accuracy, don't forget that, there's no need to redo these, but keep that in mind as you move forward. Last point would be that you seem to have a good eye for guessing where the plane's x and y lines should be after you do the corner to corner lines! So keep up the good work and keep on trucking Primus!
