Hi. Your work is pretty good but there's some things I want to point out - let's get straight into it!

For lines, your work here is pretty good. I can see that you've put a lot of efforts in your super imposed lines and ghosted lines. however, there's a bit of wobble, especially in longer lines. To solve this, you can ghost more, and remember to prioritize confidence over accuracy. I noticed that your accuracy here's pretty good, so try to keep that in your mind. Also, I can see that for some lines, especially long ones, they are a little bit curved. That may be cause by not using the shoulder pivot, but even if you used the shoulder pivot, it can still happen. If this is the case, you can consciously try to arc the line in the opposite direction. Otherwise, you work in this section is very good.

As to ellipses, they are pretty accurate, but just as I mentioned in the lines section, you need to pay more attention to getting confident ellipses than accurate ones. Remember to ghost more and don't fear to make mistakes - they are pretty hard for a beginner, so making mistakes is very normal. You seems to have understood other parts of the lesson quite well. But again, I can't stress this enough - aim on making your linework confident more than making them accurate.

Finally, boxes, you clearly have understood the underlying theory behind boxes. But just like I mentioned in the ellipses and lines section, ghost your lines, and make sure they are confident. For the rough perspective exercise, I noticed that your lines are pretty wobbly. These are supposed to be done by plotting the starting and end position for each line and then ghost, and draw the line you plotted down confidently. For the rotated boxes, although it have fell apart in quite a few places, a portion of your page showed that you have clearly understood what is the goal of this exercise. For the organic perspective exercise, I noticed that you made some perspective mistakes in the exercise, but that doesn't matter - we will work on that in the 250 box challenge.

So, all in all, your work is great, expect the fact that your lines are not confident enough throughout. So, to provide you a chance to experiment with more confident lines, I'll assign you a page of ghosted planes. Good luck with them!
