Hi, I'd like to start off by mentioning this is my first time giving feedback so take everything I say with a grain on uneducated salt.

I noticed on the table of ellipses you've only drawn through the smaller ellipses 2 times, remember in this exercise regardless of how small the ellipses are you should still draw through them 3 times. Apart from that there not much else I'd recommend in term of improvement.

It seems like you've understood all the concepts, your ghosted lines are strong, you have an understanding of perspective and vanishing points.

Remember I'm new to all this, so I would suggest listening to others aswell.
