Okay, so, the superimposed lines look good. There is the occasional fraying, so take an extra second to line up your pen, and also be mindful that you shouldn't correct their trajectory if it's off- that is to say, the line should be fully straight. The ghosted lines are a little strange. It's hard to tell if you're placing start/end points or not. (If you aren't, you absolutely should. See if you can re-read the text article for the ghosted lines exercise.) Outside of that, they're a little wobbly. Remember that priority #1 is confidence, not accuracy. It's okay for them to miss the end point. It's not okay for them to be wobbly. This extends to the planes, too, though they're looking a little better. There, be careful to not redo lines, and to not cross things out. Try to embrace the mistakes.

Moving on to the ellipses, the biggest issue is that you didn't rotate around them 2-3 times, as recommended. Refer to this: https://drawabox.com/lesson/1/11/drawingthrough It seems like you're following the remaining instructions fairly well, but this is a bit of a deal-breaker.

SO, before you move on, I'd like to see one page of the ellipses in planes exercise. For the plane half, be sure to plot start/end points for all lines, and that the lines themselves are confident. For the ellipse half, be sure to rotate around your ellipses 2-3 times, ideally 2. They should be confident first, and accurate second.

GL!
