Congratulations for completing the 250 Box Challenge!

From what I can see your line work is well done and your boxes are coming along well. When I compare your early boxes to your final sets I can see that your mark making quality improved as you progressed through the challenge. You made some good progress with your extra line weight as well. You also do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

While you have made some good progress with adding line weight to your boxes, there is still some room for improvement. The main thing is that you are not always applying your line weight correctly, which you can read about here. You should also avoid trying to correct or hide any mistakes you make during Drawabox. Once your pen touches the page, any opportunity to avoid mistakes has passed, so all you can really do is push through. Hesitation serves no purpose. Mistakes happen, but a smooth, confident mark is still useful even if it's a little off.

Finally while your converges do improve overall 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.

Congrats again and good luck with lesson 2!
