Hi. Sorry for replying so late. I discussed your submission with others who do critiques and the collective response was that it feels like you are drawing too fast. Though fraying of lines is not a problem, generally speaking but in this case the lines are fraying because you are moving too fast. Try to slow down a little. If you need help you can always ask. Its not the best but you can take a look at my lesson 1. 1 trick to help you with ellipses is as follows:
1) Draw the plane as you normally would.
2) Next imagine 4 points on each side of plane where you feel the ellipse would touch the plane.
3) Start to ghost around those points and try to touch those points while ghosting.
4) When you feel confident put the pen to paper. First thing that will happen is the sudden friction between pen and paper. Now it is easy to overshoot your lines as you put more effort into drawing the ellipse so keep that in check. Apart from theory only practice will help so make sure to do some of these exercises as your warmup.
Good luck!

I feel 1 more page of ellipses in planes would help you.
