Hi! First of all, congratulations on finishing lesson one!

I'll be going over each of the different exercises individually. If you're left with any questions, please ask.

Superimposed lines

So what I see here is that you've got fraying on both ends of your lines, something to keep in mind is to place your pen carefully at the begin of each of your lines. There also seem to be a number of arcing lines, this may be caused by not using your shoulder pivot. Another reason might be that you have a natural tendency for this, in which case you have to consciously arc a bit in the other direction. I can say though that this will definitely get better with practice.

Ghosted lines

These look good, sometimes a bit wobbly and/or arcing so remember to take your time with ghosting.

Ghosted planes

The same thing applies here, though it's good to see that you're following the advice of confidence > accuracy.

Tables of ellipses

The focus on this exercise lies in getting used to drawing ellipses in various sizes/angles/degrees and positions. This is really tough to do without a bunch of tables and rows, and as a result your ellipses don't quite fit within a set space. You also don't consistently draw through your ellipses twice, which would give you a smoother, more confident shape. It's also really useful for building muscle memory.

Ellipses in planes

There's some improvement here! Some of your ellipses do look (a tad) wobbly, so make sure to ghost as much as you need to.

Funnels

The problem here is that your ellipses don't really line up to the minor axes, you want the minor axes to cut your ellipses into two symmetrical halves. Don't worry about varying degrees yet, the most important thing here is to get your ellipses to fit snugly withing your funnels, and have them line up properly.

Plotted perspective

Nothing to add here, looks good.

Rough perspective

Remember that for this exercise you want your width/height lines to be parallel/perpendicular to your horizon respectively. Your perspective looks accurate though.

Rotated boxes

Nice attempt! It looks like you've understood the concepts and idea behind this exercise. You'll get plenty of practice in the 250 box challenge.

Organic perspective

One thing you could improve upon is darkening the line as it is closer to the viewer, and make it lighter as it gradually goes further into space. The boxes look pretty good, and as I said, there'll be plenty of practice.

Great work on lesson 1!

There's one thing I'd like you to do in order to be prepared for the following lessons.
