Heyo! I'm here to give some critique for your submission. Let's see how you did, aye?

Lines:

Your lines are smooth, clearly drawn confidently from your shoulder your shoulder. You take your time to start from the correct position, so any fraying and offsetting happens at the end of the line. This is good; you're focusing more on confidence while still attempting to be accurate. It's okay if it's not perfectly accurate, that's something that's developed while you keep going through the lessons, warmups, 50% and everything else you draw.

There is a small peculiarity in the Ghosted lines exercise: There are some extra dots here and there, next to the end points of some lines. It's not particularly relevant to the course, but it did pique my curiosity: If you don't mind telling me, why does this happen?

Ellipses:

You keep your marks confident. This is good, as ellipses are notoriously difficult to draw correctly. Some wobbliness does start to appear in Ellipses in planes and Funnels exercises, and usually that happens because the student is having a bit of difficulty hitting all the awkward angles and, in funnels' case, trying to keep the ellipses aligned. This is normal, and also something that you'll slowly get with practice and mileage. It may help you to ghost a few additional times before committing to the mark, and with smaller ellipses, pay more attention to drawing with your shoulder.

You are clearly attempting to keep the ellipses place snugly together. In funnels' case, you are also trying to keep them aligned to the minor axis. Very good job!

Boxes:

You are still keeping up with line confidence even when we're starting to draw actual shapes instead of just lines and ellipses. Very good! In Organic perspective, there are some lines that you attempted to fix by drawing the line again. When your pen touches the paper, that's the point where you can no longer avoid a mistake: Whatever kind of a line comes, no matter how wrong, let it be and move on to the next one. You might want to spend some more time plotting each corner; don't be afraid of putting down a few more dots, as those are not yet a commitment.

In Plotted perspective, you have taken your time to align the ruler, leading to only slight slanting in the back edges. The slanting happens due to very minute errors that you can try to limit by being even more careful with your ruler. There are some back edges missing in the second frame; might want to finish those.

Your Rotated boxes is good. The reason it looks more like a big box instead of a ball because there is not much converging on the edge boxes. Additionally, you haven't applied converging as much in the back sides of each box. Having said that, the result is still good for something that is considered the hardest task in lesson 1. You started the exercise by following the core steps: Drawing the five squares and the cross-hair. You applied convergence correctly most of the time, and you have drawn all boxes required. The gaps are tight and consistent, although there are some parts where they don't quite align. Remember, each neighbouring plane is basically a copy of each other; there's really no need to think much when drawing them.

Many of the boxes in Organic perspective have little if at all converging, some even slightly diverging. You might want to review the Organic perspective materials again. Additionally, ScyllaStew has made a video that talks about this; it may be worth for you to check it out. As for the rest, you have drawn a multitude of boxes roughly following the guiding line varying in size. Good work!

Conclusion:

You are off to a very good start! You have proven that you understood each exercise and have followed the instructions well. The results are as expected: While there may be some mistakes here and there, they are the kind that you will become better at the more you go through this course, the 50% rule and whatever other projects you have.

Give yourself a pat on the back, you've deserved it. Now, next up is the monster that is the 250 box challenge. Whatever problems you had with the box exercises in lesson 1 will surely be addressed here. Also, all the lesson 1 exercises are now in your warmup pool: When you start a session of drawing new Drawabox exercises, be sure to pick two or three lesson 1 exercises and doing them for 10 to 15 minutes. This is a major part of the course that will help you develop your skills further. Good luck!
