Hey. My name is Vitor Adley and today I'm going to criticize your lesson 1, highlighting problems and pointing out possible solutions. I'm going to assume that you follow the 50% rule (if not, start implementing it immediately).

Lines: when drawing a line, don't try to draw it again with the intention of correcting it if you make a mistake (it's something I saw in some of your exercises). No matter how bad the line is, don't try to fix it, just carry on as if nothing happened.

Ellipses: not bad, they have some irregularities but these will be easily corrected with practice. In the funnel exercise, I noticed that you got the alignment of some ellipses wrong, but with the intention of getting it right, then it's not a problem.

Boxes: it is in this section that what I said in the lines section becomes more evident. I noticed that in the rotated boxes exercise, some boxes had the same vanishing point, with no rotation (you could change the inclination of the box lines to have different rotations).

I will mark your lesson as complete, just pay attention to my criticisms to reduce mistakes next time. You can use some of these exercises as a warm-up before drawing.
