1.

If the endcaps of the box that the ellipses sit in are perfectly square in perspective then the cylinder will objectively be circular in that same perspective. However there can be some other perspective grid/camera lens that could make a different oval-ended cylindar look exactly like that first circular cylinder. In the same way that a lot of optical illusions like playing tricks with skewed forms that appear like boxes to the viewer and immediately collapse when you view it from a different angle.

2.

The difference in ellipse degress (minor/major axis ratio) comes from behavior of perspective and the dimensions of the box remaining constant. So, yes that is one indication that you got it correct.

That is where I am at with my understanding anyway. I hope that answers your questions.

I am not nearly as far as you so I won't answer in regards to any official DrawaBox way. I will just answer for the other 50% of drawing for fun.

I suspect that you would be better off simplifying the forms to the point where the intersecting feathers are mostly just texture - with only a slight consideration to how the feathers would impact the outer contour of the wings. Rather than trying to wrap your head around all the layers of feathers and how they interact.

Here is a video from John Muir Laws on youtube that might help with drawing bird wings. https://www.youtube.com/watch?v=aGzpRSN1X3A

He has a bunch of other videos on a lot of animals. And more on birds.

There is also Aaron Blaise. I know he has a huge series of videos on drawing specific birds but I am not sure how much of it is free on his youtube channel.

I hope that helps.

Put the straight edge along the lines of the box you drew and draw that line - wherever that line takes you. If there are three sets of 4 lines, each perfectly leading you to three distinct points, congratulations, you are a robot.

For the 250 box challenge you are not supposed to pick vanishing ponts before hand and try to draw to them. Instead, you are meant to develop an intuition about the direction all the edges are converging.

Go to other people's submitted box challenges and look at how they did it.

Or, review the written material and rewatch the video here:

There isn't a single set distance between the two VP's needed in order to get 90 degrees. The distance will depend on the type of lens effect you want to produce.

Here is a video timestamped to the relevant parts about lenses

https://youtu.be/2XF5YuAK63I?t=251

In short, if you want a dramatic, distorted, look then bring the two VP's closer together. This emulates a wide-angle camera lens.

If you want to get closer to an isographic, more regular, look then you spread them further apart. That emulates a long-angle camera lens.

So, with all that said, that doesn't really help you get a good box like you were asking for. I recommend starting off practicing what is called the Y-Method. IIRC Uncomfortable mentions it in the box challenge material. In any case, the Y-method has you draw the closest corner/edges first and.

The discord has this image pinned in their Lesson 1 channel that might help:

https://cdn.discordapp.com/attachments/368870697742630912/384092950700752896/BoxDemo.png

Notice that the image states the angles between the lines should never be less than 90 when using the Y-method. (You'll also see what is called The Arrow Method for when you have a 2-point-perspective box that is placed directly in front of the horizon line. I'd say stick with the Y-method until you get the hang of it.)

I feel this video from Proko does a good job breaking down the intuitions you are wanting to develop as you draw a box using the Y-method:

https://youtu.be/3uEtdDvK6Xo?t=308

It isn't timestamped exactly to the Y-method part but it is worth watching the entire segment, in my opinion, so I timestamped it there.

That more or less been my experience too.

I've had luck combatting the boredom by finding like-minded people on Discord. We go into a voice chat and all pick prompts/reference images then try to draw them while we talk. It has helped me stick with the 50:50 rule a bit more consistently.

I feel like part the reason for the 50:50 rule is so we can start working on our outlook and find the enjoyment of the process, appreciate the small wins, and find ways to apply the principles DaB to our own work.

Also, boredom isn't the end of the world. Going through life being entertained 24/7 isn't likely to give us the most fulfilling life. Sometimes you have to put down short term gratification for the sake of long-term goals. I feel like those accomplishments are going to stick with us longer.

I think they forgot to mark your lesson as complete with their critique. I just made a critique that marks it as complete. If two people agree with me you should be good to go. If that doesn't work I don't know what else it could be.

I hope this helps!

You asked in a discussion board why you don't have a badge for this lesson. I suspect the person who critiqued you forgot to mark it as completed. I think they did a great job with their input and agree with them that you are good to move on. So I am marking it as complete to see if this solves your problem.

Next Steps:

Move on to the next lesson.

This community member feels the lesson should be marked as complete, and 2 others agree. The student has earned their completion badge for this lesson and should feel confident in moving onto the next lesson.

Love Life Drawing on youtube has a great video on mastering contour lines. It is definitely worth a watch.

So, what you are correctly identifying here is that there is the center of an ellipse, and then there is the center of the circle in perspective that the ellipse represents. In the same way the X finds the center of the plane in perspective but if you were to take a ruler and divide up sides of the quadrilateral into equal lengths you'd get a different center. The major axis of the ellipse does not necessarily go through the perspective center of the of the circle.

So you asked for more info on this. The first time this clicked for me was when watching Marshall Vandruff's 1994 perspective course. He pointed this out and referenced the Perspective Drawing Handbook by Joseph D'Amelio, pages 83 and 84. I found images of them for you: https://imgur.com/a/1P4X2iK

Notice where the bucket handles attach on the bottom left of page 84. The difference is due to the forms converging to vanishing points. Just like a box's edges, the length of rim closer to the viewer will be larger and the further will be smaller, causing the discrepency.

edit:

As for how to more accurately place the inner circle, you could do a plan projection of both confining squares like the diagrams show here: https://www.joshuanava.biz/technical/i-hli.html That would be the most accurate, but it is a lot of work.

Or decide where one corner of the inner plane is located, then mirror that one corner's location to the 3 otherspots by using the parent plane's diagonals. A square's corners, when centered in another square should always fall on the larger square's diagonals and the corrosponding sides should be parallel. So you can get by with picking a point on a diagonal, drawing the side of you box to the corrospoing side's vp, see where that new side intersects the next diagonal, and repeat. When you get the inner square mapped you can draw in a smaller ellipse the same way you did the larger.

If you have a bit of isopopyl alcohol you can pop off the metal nib and drip a bit in there to revive the dried out ink. There should be a little notch in the plastic where it meets the metal nib. You can take a needle or thumbtack and wiggle it in that hole. It should come off pretty easily. You can look up videos on youtube for how to refill microns. They'll show you how to do it.

I wouldn't say it is necessary to redo the ones you've done already. You'll revisit the exercises in the future for warmups anyway.

Tips:

Keep the pen at a 90 degree angle to the paper. Don't press hard. I've found that the superimposed lines exercise does a real number on the felt regardless of hand-pressure. Something about the repeated, fast, friction against the ink already on the paper causes it to destroy the tips particularly fast in my experience. ymmv I generally don't revisit that exercise too often. Instead I just do parallel lines for warmups(or use a different pen).

As an alternative I've also used Pilot Precise V5's and thought it was pretty comparable line-quality wise. If you are in the US you should be able to find some at your local big-box store. It works out to be about \$1.50/ea The ink isn't archival quality so it will fade to blue after a while. Also be aware that using a rollerball pen can leave trenches in the paper that can throw you off. So again, don't press hard.

I hope that helps! Best of luck and stick with it! :)

### PureRef

This is another one of those things that aren't sold through Amazon, so I don't get a commission on it - but it's just too good to leave out. PureRef is a fantastic piece of software that is both Windows and Mac compatible. It's used for collecting reference and compiling them into a moodboard. You can move them around freely, have them automatically arranged, zoom in/out and even scale/flip/rotate images as you please. If needed, you can also add little text notes.

When starting on a project, I'll often open it up and start dragging reference images off the internet onto the board. When I'm done, I'll save out a '.pur' file, which embeds all the images. They can get pretty big, but are way more convenient than hauling around folders full of separate images.

Did I mention you can get it for free? The developer allows you to pay whatever amount you want for it. They recommend \$5, but they'll allow you to take it for nothing. Really though, with software this versatile and polished, you really should throw them a few bucks if you pick it up. It's more than worth it.
