Hi there Tastyart! First of all I wanted to say that I am very very VERY incompetent at giving much advice on this, but I wanted to drop by to tell you that when you finish a lesson, you should probably post it not in your sketchbook, but in the lessons and homework category. This way, others can mark your lesson as complete and maybe even request revisions.

Now, from the quick glance I took at your pages, I can tell that you understand the concept of ghosting and are applying it pretty well!

The Elipses in the Tables of Elipses Exercise overlap a little, but that's ok! You are not chasing perfection and you are going to have plenty of time to practice it in your warm-up sessions.

The Ghosted Planes + Elipses look awesome and I appreciate your precision, the same can be said about the Funnels Exercise.

The Perspective exercises don't look absolutely perfect, but I can see that you understood the concept and, once again, practicing being more confident and doing ghosted lines warm-ups will help you a ton! Sometimes I don't get these right either so don't worry :D

In the Rotated Boxes you missed the little corner box, which is a pain to make, but you should try to do it, you got this!

The Organic Perspective Exercise looks pretty nice! Maybe the foreground boxes could be a little bigger and also they don't necessarily need to appear in the predefined space, they could also go a little more off screen.

Now, I think you did an awesome job, but please post this in the Homework category so that it can be marked as completed! Have a great day pal!
