I think you're getting the lessons, this looks like good work. On your first page of superimposed lines you had some fraying at both ends. That implies that you weren't putting your pen down on the same spot to start your stroke but you got a handle on that later on.

The ellipses look good but I would recommend doing them larger. Drawing both small and large ellipses now will help you out later on.

The organic perspective exercise is rough, but that's understandable cause this is lesson 1. Mine looked just as rough, if not worse lol. Just keep in mind that the most important thing about drawing a 3d box imo is that lines always converge towards a point away from the camera. If you keep that in mind and force yourself to stick to it, most other mistakes are forgiveable and things will look better.

I would recommend you continue doing the ghosted planes exercise to get your line confidence up. Don't make them all the same size, do them big and small and fill them with ellipses.

I will mark this as complete.

Good job finishing lesson 1!

Though I'll let you know that the next step suggested by the current reviewer is incorrect, and before going to lesson 2 it is required to complete the 250 box challenge first.

Good luck!
