Hi! Starting with your line exercises. Your superimposed lines are pretty accurate overall, especially given the length of lines you're drawing. Your ghosted lines and ghosted planes are also good. One thing to watch out for here is some of the lines tend to wobble a bit - make sure you're drawing though all your lines with confidence.

Your tables of ellipses are good in terms of accuracy and consistency, but on a few occasions you're lax on making sure the ellipses overlap with each other. Same goes for your ellipses in planes, regarding the ellipses meeting the edges of the plane. Your funnels are, on the whole, pretty good. There's definite improvement in the ellipses here.

On your rough perspective boxes, your lines could be improved. There are wobbles in places; additionally your horizontal lines should always be parallel with the horizon line, and your vertical lines perpendicular to it. The lines are improved upon in the organic perspective exercise. The biggest thing to improve on here would be your box construction, making sure the lines are converging to the vanishing points. It looks like you've already done the box challenge though, so I hope that improved your understanding! Well done for finishing lesson 1.
