Hey, nice job finishing the challenge!

One thing to look out for is re-drawing lines that you made a mistake with. You should just leave mistakes as they are, trying to "fix" them only draws more attention to them.

Overall you show nice improvement and I think you get the gist of what this challenge is about.

This graphic shows a quite useful way to think about your parallel lines in space, keep up with your boxes in your warmups and goodluck!!
