Hello! Congratulation for finish the first lesson in DaB!

Well, for the short, you seems understand the entire exercise of the lesson 1. You only need more practice. Most of your lines are still wobbly and arching, it mean you're probably use your wrist pivot instead shoulder pivot. It can be seen in your Ghosting Lines. Though, you show improvement in next homeworks.

For ellipses, many of them look not smooth and not confident. Take your time for doing ghosting method. But I guess, it enough.

No much issue on your VP perspective despite the lines. However, here the things that you need to remember: In Rough Perspective that have one point of VP drawn, width lines should be parallel to horizon and height lines perpendicular to horizon.
