Followed the video. Great information. Never thought of it that way. did a couple. to make the technique clear in my head. hope it comes across clear on paper.

Some things clicked after this lesson - i) orthos are not just reference, you can use them as you draw to solve problems ii) building the box and scaffolding first is a very good idea before attempting curves iii) tracing paper is great for problem solving… As the penny dropped it gave confidence to try and solve a problem I’ve wondered about and tried to freehand intuitively with poor results; a hollow open canoe-like form in vertical perspective with a lot of foreshortening…so curves in perspective. Tried a simple oblique view first then tipped the canoe vertical for more extreme ~worms-eye view. Well, the results were a lot more successful than freehand intuition…! Also learned a pencil eraser works to remove ink on tracing paper. Useful stuff. 🤩

ah, I did much better than I expected :) Tried to do a bit of a curved perspective with the top one. Though I don't think it 100% worked, it was a good time none the less

I tried to do the twists intuitively without drawing boxes but keeping the concept of a box rotating at the back of my mind. I first drew approximately a simpler version like a ribbon of negligible width and then added depth and tracked the depth throughout using x-ray vision. The colored dots are added as the last step to double check if the edges of the box (imaginary) align correctly throughout. I think I have made a few mistakes in proportion, regarding keeping the width steady and in perspective. It looks right to me but my eyes are not much trained, though.

I am still in the failing stage and I will be here for a while ;). I found this resource from a Proko student which is the 3D grid model of the rectangle twisting. I thought it was a nice extra to share with the rest and see if you are like me, that I am still trying to wrap my head around this https://practicedrawingthis.com/3d/model-twisted-box.html

This is tricky

Marshall, It was a complete surprise to discover my arrow used as an illustration in this lesson, and I have to admit I’m a bit flattered—haha! I didn’t give it much thought when I drew that arrow, and now that I’ve seen and tried to follow your lesson, I couldn’t resist taking on the challenge myself—this time more thoughtfully. I hope I passed; it’s a very difficult task but so rewarding to develop this technique "scientifically" and explore this "P.O.V."

gave it a couple tries then came up with one or my own. Ben letting my lead dull out. I can do about half of what Marshall is using before hitting the lead sharpener. I will eventually make it work.
