Hello,

I see your work and a good thing that I can say is that it's a progressive in positive work.

Lines : You start infact pretty rough on super imposed lines especially in longer lines but then take some patience and do better on ghosted lines and ghosted planes.

I appreciate that you add some curves.

Ellipses :Same for the ellipses.

Rough on table of ellipses but then better in ellipses in planes and much more in funnels.

So for those two (super imposed line and table of ellipses) I suggest you, through next lesson, to stop on them as a warm-up a little bit more.

Rough perspective :Only 'cause I know that you have now to deal with the 250 box challenge, the one advice I can give you is to do 1 page more of rough perspective before tackle that next lesson.

Rotated boxes and organic perspective :

You're done a good job on this.

The only thing I may suggest you, referring only on the organic perspective, is to try not to correct the lines you've done with another line.

The purpose of using the felt-tip pen is precisely to see the mistakes so to know where we have to improve.

That's it, I hope my review will be clear enough and useful.

Have a great continuation of exercising and having fun. :)
