Congrats to have done the 250 box challenge !

Well let's start, first of all sometimes you lines are extending in the wrong direction, I saw that at the beginning of your challenge and at the end so you should correct that point. Secondly your lines are too parallel and they are sometimes diverging so watch out !

Here a link to understand that : https://imgur.com/mWLlnYl

  1. Your hatching lines are pretty messy, many times I saw that you didn't know which face was facing to you.

  2. I noticed that you was struggling with your lines to end at a point. When you was failed with your lines you was trying to redo them but you should probably do not that and always use ghosting method.

  3. You should draw more of diversity in your box, a lot are similar.

  4. Your box are too small they must take all the page when you draw 5 or 6.

  5. And last something that I tell to all my critiques because It's really usefull : Inner corner, A way to improve them is to start thinking about the relationships between lines instead of just thinking about the lines in pairs. When drawing the lines of the boxes, the student should keep in mind all the other lines in the set, comparing their angles and making a guess based on them. This diagram explain this more clearly:

The diagram can be pretty hard to understand at first, so if you don't understand it, don't get frustrated, keep reading it from time to time while practicing regularly, and it will click eventually.

A thing I've found that helped me inmediately to improve the inner corner while I was doing the challenge is to change the order I drew boxes in. By drawing the inner corner before the last line of the box, I found it easier to use the previously mentioned info of thinking about the relationship between lines, and made it easier for me to get the convergences right. Here's the order I'm talking about:

This takes into advantage something explained in the rotated boxes exercise too (taking advantage of lines that are very close), so give a look at the page if you want to know more about it.
