Yeah, this one works. Congrats on completing the challenge and now to check your homework. So after looking over your submission I'm noticing some problematic trends and issues popping up that we are going to need to address. Starting with a positive though I do want to say that your linework on these boxes was quite good and you used the ghosting method very well throughout and I did notice quite a bit of improvement on that front. Now onto the more problematic stuff. On the very first page, despite all of the convergence issues you were having, you did actually extend the lines correctly on all of your boxes. However, after looking at the rest of your pages I don't think you really understand how or why you are doing this and I'm not really sure you understand how drawing boxes in perspective works in general because there seems to be a pretty big regression in understanding as you worked through the rest of this challenge. The more you worked through the challenge the more you pretty consistently extended lines in the wrong direction. https://drawabox.com/lesson/250boxes/1/wrongdirection Please check the lesson notes here. I'm also going to quote this because I think it's very relevant for you.

"Our lines must be extended AWAY from the viewer, towards the implied vanishing point, never towards the viewer. Make sure that when you are about to extend your lines, that you think about which side of the box is pointing towards you, the viewer.

Sometimes students will feel that they need to extend their lines in the direction that they converge, but this is incorrect. Sometimes, because we have drawn the initial box incorrectly, our lines will diverge as they move farther away from us. This is the kind of mistake we are trying to identify by extending the lines."

This is especially evident in #164 where you extended the lines in the wrong direction for every single side and part of that is because your initial construction has lots of divergence issues. Also take a look at this graphic as it will help you focus on what you should really be thinking about when you construct a box. https://i.imgur.com/8PqQLE0.png When you are drawing a box in perspective, all lines that are receding away from the viewer will ALWAYS be converging towards a vanishing point and never diverging as they move back. If the lines are diverging at all while moving back in space that means a box is growing in size as you look at it in space. The same is true for using parallel lines for boxes that are in 3 point perspective. If a box in 3 point perspective has ANY parallel lines that means it is growing in size as it moves back into space since any box that is in perspective will have lines that will ALWAYS converge towards a vanishing point even if only by a slight amount. If the lines don't converge but simply remain parallel or even diverge that means the box is getting bigger as it moves back in perspective. You really want to burn this idea into your brain.

You do have some well constructed boxes with some lines extended in the wrong directions like #199 and #240 but these appear to be a rarity. You also seemed to get into a habit of using parallel lines while constructing your boxes to get away from having to deal with convergences which helped some of your boxes feel a bit more solid, but looking over your work in general here I'm not getting a strong sense that really understand how draw boxes in perspective correctly. I think there are some pretty fundamental misunderstandings here about how boxes are drawn in perspective and my advice to you would be to simply read all of the lesson materials again and watch the video again. I would like you to do 50 more boxes after going over all of this material again and I want the lines to be extended correctly for all of these.
