Remember that when doing critiques, we don't actually worry about students' self-assessments. It's a little late to remind you of this now, since you're about to have the lesson and course marked as complete, but in general it's best to just submit your work and let it stand for itself. The work itself will tell us where you struggled, and whether it was actually significant to what you were meant to learn in the course, or whether it was not such a relevant concern.

I'm very happy with your results here, and I feel you've mostly addressed the points I raised previously. You've been vastly more meticulous in both drawings, and have shown a great deal of care in building out each car with careful attention to ensuring that there is always enough structure to support whatever element you wish to add next.

There is just one issue that still comes up, and it's something I have called out many times. As shown here, you're still drawing some curving lines without the appropriate structure to support it being in place ahead of time. Instead of jumping in with a curved line, you need to be blocking out that structure with straight lines first, then rounding off the corners as needed.

Now, I'm not going to dwell on that - I'll leave it to you to address it yourself, because I have indeed mentioned it in basically every critique I've offered you. Everything else is much better and you're showing far more patience and care through each construction so I'm going to go ahead and mark this lesson, and the course with it, complete.

Congratulations.
