Hi Gababa, congratulations on completing lesson 1! I'll be taking a look at your work.

Lines:

Super imposed lines:

Your lines look smooth & confidently executed, with no fraying at the start of the line. This shows that you took the time to carfully plan and make your marks. I only saw a bit of wobbling for the short lines on the second page and on the curves. Remember to put confidence first when practising these in the future. Your longer lines tend to have a small arch, but there's a visible improvement form page one to two. Try to arch your lines in the opposite direction if you encounter this again to counteract the curving.

Ghosted lines & ghosted planes exercices are good. Your lines look smooth and your accuracy improved over the course of the excercices.

Ellipses:

Tables of ellipses & ellipses in planes:

Your ellipses are nicely drawn. You've drawn through them and made efforts to fit them snugly in the tables/planes. But some ellipses are a little deformed, meaning that they are not symmetrical if you devide them in to two halves with the minor axis. Maybe try to experiment a bit with the speed at which you draw them. Some people find it easier to draw even ellipses when drawing a bit slower, and others when they execute their marks faster. Also don't forget to ghost your ellipses a couple of times first before drawing.

You did a good job with the funnels as well. I have the same remark for this exercise as for the previous two exercices. Also be mindful the keep the line representing the minor axis (the long horizontal one) in the middle of your ellipses, placing it so your ellipse is devided into two equal/symmetrical halves. Ellipses & the concept of the minor axis will return in lesson 2, so it's a good thing to keep in mind.

Boxes:

For the first frame of the plotted perspective, one box (the outer left one) is drawn outside of the two vanishing points. This can make it appear distorted. See this link for more info about distortion with two point perspective: https://drawabox.com/lesson/1/10/distortion

The other boxes look great, they have clean linework and fall nicely in between the vanishing points.

The rough perspective exercice is completed well. Your depth lines are extended correctly and the convergences improved from the first page to the second. On page one, some of your width lines aren't parallel and a few height lines aren't perpendicular the the horizon line. But I see you corrected this on page two, good job.

Rotated boxes looks solid, they feel 3D and have rotation. Don't worry about this exercise. Its purpose is just to introduce you to how the concergences of a box change as the vanishing points slide across the horizon line. You'll get plenty of practice with convergence with the 250 box challenge later.

Your organic perspective pages are good. The boxes flow well accross the frame and you've varied the oriëntations of your forms.

Overall this is a really solid submission. You've shown you have a good grasp on the concepts of lesson 1.
