Hello Eikyu, congratulations on completing lesson one. I, Meownsterhunter will be critiquing your work.

Lines:

Your lines are confident , have a defined starting point .These are off to a fine start. Fraying on the end is expected , nothing to worry about there. A little bit of arching on the longer lines - which can be fixed by trying to arch consciously to the opposite direction .

Ghosted lines are accurate and confident ! Good job on these.

One thing i would like to point out that you are not plotting the points when bisecting the planes on the ghosted planes exercise.

Ellipses:

Fantastic work on the ellipses! They are smooth , drawn through 2 times and most importantly confident. One thing to keep in mind though some ellipses are going out of bound . Other than that I am very impressed on your table of ellipses.

Again fine work on the ellipses in plane exercise.

Your funnels do have some common minor axes alignment issue. you can read more about that :https://drawabox.com/lesson/1/13/notaligned .

Boxes:

The plotted and rough perspective looks great. One thing to remember when doing a one point perspective exercise is to realize that all of your horizontal lines should be parallel to the horizon line and all of your verticals should be straight up and down .

Your rotated box exercise turned out pretty well. Four boxes on the lower right corner have a bit of rotation issue and are deformed . Other than that you have done pretty good job.

On the organic perspective you could have changed the dimensions of boxes a bit more rapidly to give it a bit more depth -which you have done your second page.

Overall this was a solid submission. I think you understand most of the concepts these lessons are trying to convey. Good luck on the 250 box challenge.
