You made it through the monster challenge! Great work!

Yes, there's a lot of improvement. Your line quality improved fairly quickly, as did your hatching. You also did a large variety of boxes. You clearly have developed a sense of how the convergences need to go.

As a minor thing, I notice that in your ultra long boxes (in the 220's), the long lines have a bit of a bend. Way to jump outside your comfort zone! Adding line weight looked especially difficult. For warm ups, you may want to do some long frayed lines, or lines that go "point to point" over a comparable distance so you can make long, straight, confident lines.

You'll also want to do ellipses and curved lines for warmups if you haven't recently, cause that becomes important in the next several lessons.

Overall, great improvement and you are well on the path! Onward!
