Hi Tom1406, good job getting things done with lesson one! I will handle your critique for this lesson's exercises. I can already tell it won't be very look, since even at a first glance it is looks clear to me that you have a solid grasp on the concepts presented in this lesson. Still, I will try to divide this critique in sections corresponding to each exercise.

Superimposed lines

Your lines look for the most part confident and improve gradually from the first to the second page. There's fraying on one end only as it should be. I see you've also put a lot of effort in trying to experiment with curved lines, which is good.

Ghosted lines

Not much to say here either. Your lines are confident and without wobbling. There's virtually no arching at all and each line goes almost straight from one fixed point to the other with little drifting. You also show already good line control, with very little overshooting or undershooting most of the time.

Ghosted planes

You applied well the principles of the previous exercise to this slightly more complicated case. You are again very precise and confident. Only as a minor note, I feel you could have used the space in the first page in a more efficient way since the bottom of the page is a bit empty compared to the rest. You did however corrected your shot in the second page, so that's good.

Tables of ellipses

Your ellipses look fluid, confident and more or less symmetrical. You correctly draw at least 2 times through each one and manage to stay fairly close the bounds of the table and neighboring ellipses, with precision improving as you go forward.

Ellipses in planes

Pretty much everything above applies here. You manage to make your ellipses confidently while clearly putting in the effort to make each ellipse touch all four sides of the plane. As a result a couple of ellipses end up looking a bit wonky but most of them remain fairly symmetrical.

Funnels

Each individual ellipse look mostly good in isolation, with all the upsides described in the 2 previous sections. As a whole, most of the ellipses are cut in half by the major axis of their funnel. In a couple of funnels however some ellipses are a bit slanted respective to said axis. Also, in some funnels the ellipses are a bit too much spaced, while they should fit snugly between each other. That said, I think you generally understood and applied the goals of the exercise.

Plotted perspective

Not much to say here. You apply 2 point perspective correctly and draw through each box.

Rough perspective

The linework looks for the most part confident. You have correctly drawn through your boxes and made only one set of lines per box convergent to the VP, as is required in 1 point perspective. Your line extensions for most boxes go roughly towards the VP, showing already a good sense for direction and depth in 3D space.

Rotated boxes

Now we enter the final and hardest parts of the exercises, and let me say that I feel you managed to tackle them really well. Specifically for this exercise, your boxes are kept tight and rotate well, creating a nice spherical shape. The 4 corners between the initial cross in particular is well handled. As a minor critique, your hatching in some section looks quite messy, having 2 sets of different hatching lines crossing each other. Unless stated otherwise, hatching in this course should always be applied in one direction only, with evenly spaced lines made using the ghosting method.

Organic perspective

You did well here too. The boxes follow nicely the initial curve, and get bigger coming closer towards the viewer. I see that you also were not afraid to draw overlapping boxes, which is good since it helps to understand how objects relate to each other in space. Some boxes look a bit wonky, but don't worry too much about it, you will have plenty of time to practice in the 250 boxes challenge, and besides getting the boxes "right" wasn't the focus of the exercise.

Final remarks

I think your did very well in this first lesson. A few errors aside, you have shown that you understood and are able to apply the concepts presented in each section. In my opinion, you are more than ready to move on to the 250 boxes challenge. If you want to get your badge, you could post your submission on the official discord and ask if some users want to check and agree with this review. Good luck and keep up the good work!
