Congratulations on completing the 250 Box Challenge!

You did a really good job overall. Your boxes are consistently well constructed with smooth, confident looking lines and the quality of your mark making continued to improve as you worked your way through the challenge. Your additional line weight also becomes much more subtle and blends in better with your previous marks. Lastly, when I compare your early boxes to your final few pages I can see your sets of parallel lines do a better job of converging towards their shared vanishing points.

I think this diagram will help you further develop that skill as you continue through Drawabox. So, when you are looking at your sets of lines you want to be focusing only on the lines that share a vanishing point. This does not include lines that share a corner or a plane, only lines that converge towards the same vanishing point. Now when you think of those lines, including those that have not been drawn, you can think about the angles from which they leave the vanishing point. Usually the middle lines have a small angle between them, and this angle will become negligible by the time they reach the box. This can serve as a useful hint.

You did really well on this challenge and I think with the diagram and more practice you will continue to see improvement. Congrats again and good luck with lesson 2!
