Congratulations on completing the 250 Box Challenge!

You did a good job on the challenge overall and I can see that as you progressed, you made a lot of improvements with the quality of your mark making. Your lines steadily become straighter and more confident looking. You drew your boxes at good sizes with a variety of orientation and foreshortening. You also do a better job of getting your sets of parallel lines to converge more consistently towards their shared vanishing points!

I can see that in some areas you tried to add extra line weight to your boxes, which you can read about here. It looks like you weren't always applying your line weight correctly though and sometimes you may have used it to hide or correct mistakes. 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 original mark. This will allow you to create more subtle and clean looking weight to your lines that reinforces the illusion of solidity in your boxes/forms. Make sure that you are also focusing the extra line weight along the outer edges of your form. This is something that you will improve with consistent practice, so make sure that you include this step in your regular warm ups.

Something else to keep in mind, while working through Drawabox you should never hide or correct any mistake you will make. 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. You should also make sure that you are taking your time and using the ghosting method for every mark you make, including the hatching that we sometimes use for our boxes.

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.

Congrats again and good luck with lesson 2!
