Congratulations on completing the 250 Box Challenge!

You did a good job overall and I can see you made a lot of improvements by the end. By the end of the lesson you do a better job of constructing your boxes with smooth, confident looking lines. I can also see that you did a pretty good job of adding some additional line weight to many of your boxes and you do a better job of getting your sets of parallel lines to converge consistently towards their shared vanishing points!

I can see towards the end of this challenge that you still struggle a bit with adding line weight to your boxes. When you go to add weight to a line it is important that you treat the added weight the same way you would a brand new line. That means taking your time to plan and ghost through your mark so that when you go to execute it the mark blends seamlessly with your previous mark. This will allow you to build and create more subtle and clean looking weight to your lines. You should also avoid making any sort of "correction" marks or hiding mistakes. Just remember that the confidence of the stroke is far and away your top priority. Accuracy is something that you will improve on as you continue working through Drawabox and practice ghosting. Even after 250 boxes you are not expected to be accurate 100% of the time. Just do the best you can and move on.

Finally while your convergences 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.

You did a good job overall and I can see that you made a lot of progress. Congrats again and good luck with lesson 2!
