Hi, thank you so much for your in depth feedback I really appreciate it. It's massively helpful to gain some outside critique and perspective on my work. I am going to continue to work on executing more confident lines (no wobbles), as well as tightening up my ellipses and keeping them consistent to a minor axis. I have completed the additional page of 'ellipses in planes' which I have added to my imgur submission here: https://imgur.com/a/uszc5eJ . I must have read the instructions incorrectly when it came to the number of pages to submit. Thanks so much again for all your help!
