Congrats! I'll split up the critique into 3 sections: lines, ellipses and boxes.

Lines:

Good job on the superimposed lines. I can see you improved as you worked through them too - your second page shows less fraying and the lines are straighter than the first page. The wobbles in your lines likely come from overthinking the line a bit, so just use this exercise to warm up and focus on straight, confident lines more than accurate lines. In the future, do a few of these as a warm up, e.g. a few long and a few short to help practice your line confidence. Your ghosted lines are ok, but they do wobble a bit. Again the solution is confidence, and you can build confidence by making sure you ghost the lines plenty before drawing them. Ghost a few times deliberately and confidently, and then repeat the motion with your on the paper. You'll get lots of practice in the box challenge though! Ghosted planes are pretty good on the whole, you over- and undershot a bit on some of the sides but this is better than going too slow and wobbling, Placing the dots carefully on the corners and sides of the planes has meant you have fairly good accuracy overall. As i said earlier, just make sure you're not rushing - take your time ghosting confidently.

Ellipses:

You used the soace well with your table of ellipses and have varied the sizes and degrees well, so that's good to see. Some of your ellipses are a bit deformed though, and are a bit egg or sausage shaped rather than true ellipses. On the other hand, some of them are very good so you clearly have the ability, and you will get there with practice as long as you remember to ghost and draw from your shoulder. The same can be said for your ellipses in planes - some are very good and some are a bit deformed, but no major issues. Your funnels look alright too, but do you see that some of them are not aligned to the minor axis? They aren't symmetrical along the line that cuts them in half, which means they end up looking a bit lopsided. However, this is not all of them and you have done a good job overall.

Boxes:

Plotted perspective is very nice and clear. Some of your verticals don't quite look vertical, but overall good and you have kept track of all the lines well. Rough perspective looks good and you have extended the lines properly, which is a good skill to have. On the whole the lines are getting pretty close to the vanishing point, which is great! The main thing to watch out f9r is that your back face should match the front face in terms of shape. Some of yours look a bit distorted - when you plot out the dots for the back face make sure it matches the front. If the front is a square then the back should be a square too, for example. Great job on the rotated boxes - this isn't an easy exercise but you've made a good job of it. Just again remember to watch the back faces of your boxes. If the back faces don't match then it's a good indication that your vanishing points are different for different edges, I can see a bit of a mismatch on the box directly to the right of your centre box, whre the back looks wider than the front. Nice job on organic perspective too, but watch the angles in your starting Y shape - none should be less than 90 degrees otherwise you will end up with distortion, i can see a couple like that. Some of your lines are diverging rather than converging to the vanishing point, but you'll get more practice identifying and fixing that in the box challenge.

Overall nice job on Lesson 1! Have a look through and make sure you can see what I've pointed out above.
