I will start by saying that I am super impressed with your work, all of these do look very well executed to me and the things I'm about to mention are minor things that I am sure that you will be able to sort out really quickly. Well done completing lesson one! Now, onto the actual critique

Lines

Your superimposed lines do have some fraying, but as stated in the lesson, this is not an issue for now! A few of your curves have fraying at both ends but it does not look like a consistent issue to me, maybe just try to be aware of it in the future. Though, most of the time you likely won't be going over the same line that many times so it's not really an issue.

Your ghosted lines are really smooth but some of them arc slightly, mainly towards the end, like they are trailing off a bit. I'm going to be honest in saying that I do not know what causes this and therefore can't give that much solid advice other than be mindful of it, and keep your eyes on your target point.

Your Ghosted planes (and the planes part of the elipses in planes) do show a slight arc in your lines as well, but, it seems that you are improving much along the way, the last two planes are better than your first two, so again, not really a major issue, just something to be wary of.

Elipses

Your tables of elipses are honestly goals. I bow to you and applaud you!

Your elipses in planes are generally good, there are a few that are floating, not touching all sides of the plane, and a few that are a little bit uneven but it is nothing I'd spend too much time on trying to perfect. They are absolutely fine and good!

The funnels do look great to me, both minor and major axis seems to be correct in every single one, great job!

Boxes

Plotted perspective looks amazing to me, you clearly got a good grasp of perspective!

Rough Perspective is looking a little shaky, the perspective is absolutely okay, you're doing better than I did with actually making the perspective work, however, your lines here do arc quite a lot and I suspect that is what is throwing you off. While I won't say "redo this" or assign you a revision (because you have shown earlier that you do know how to, and can do, lines that arc less) please be mindful of this in the 250 box challenge!

Your rotated boxes is giving me major art envy, and your lines are back to being nice and un-arc-y again. Really well done!

Organic perspective looks really rather well done to me, the first page has some wonky boxes but you had that sorted out by page two so I will just repeat myself and say Well done once again!

Congrats on completing your homework! I would say move on to the 250 box challenge now, just keep in mind to try and not arc your lines and I think this will be smooth sailing!
