Hey Sirap! Congratulations on finishing lesson 1, that's huge! I'm Gady and I'll be reviewing your work, so let's see what's left to be said.

Lines

I can already see you are developing confident lines. You managed to craft your superimposed lines fraying only on one end, taking care of approaching them from one specific point. There's a little bit of wobbling, for sure, but it's not that noticeable and you will gain confidence with practice. Remember that confidence is more important than accuracy here. You'll develop accuracy with time, you'll gain confidence with practice. Other than that, I'd say good job.

Ellipses

I'd say the biggest problem in your submission are ellipses. To begin with, on table of ellipses it seems as if you didn't have specific goals for each section: the whole pages look a bit random, like you weren't striving for angles, sizes or positions of ellipses. To have goals for each ellipse is important, because you can evaluate your results with specific criteria.

Secondly, I noticed you are drawing through 2 or 3 times, that's good. However, most of your ellipses are wobbly. This can also be seen on ghosted ellipses and funnels. On funnels, you have to be aware that the minor axis should always bisect the ellipses, as this is not the case in some bits of your work.

All of this, obviously, can (and will) be improved by practice, as they are particularly difficult excercises.

Boxes

I think this is a good first approach at perspective. I noticed one mistake, though: when extending lines to horizon line to check how your convergences went, you dismissed the actual angles of the lines you made and just forced all the lines to converge at the VP. This is not useful, as it does not give you an accurate understanding of how you did. Be aware that on rough perspective width lines should be (and in your work sometimes are not) parallel to horizon, and height lines should be (and in your work sometimes are not) perpendicular to horizon. This is a hard task, but it's good to keep in mind so you can get better at it.

I'm not sure if I'm adding any new feedback to the one you received about rotated boxes, but keep in mind the last vertical rowes from each end are almost converging and therefore not rotating, as you can see in this diagram: https://d15v304a6xpq4b.cloudfront.net/lesson_images/d73eea49.jpg

Only thing I'd say about organic perspective is that maybe you were a little too shy overlapping the boxes. Overlapping in perspective is a good thing: it gives your drawing a lot of sense of depth. But you will get this later on. Other than that, pretty good job.

One thing I'd add to this sections is the messy hatching you applied to the boxes. As hatching is optional, if you decide to do it, you should do it with the exact same care as you draw every line on the course.

Final thoughts

All in all, this is a good job. The main thing you should practice from now on is confidence when drawing lines and specially ellipses. I'll suggest a little revision to help with that.
