• superimposed lines:

on one page the starting end ending points of the lines are cropped and the pages aren't numbered so its hard to tell if you've improved, but on some lines there is fraying on both sides, while fraying on the end is mostly fine, be sure to take some time to place your pen on the starting dot before executing the line

• ghosted lines:

some lines wobble a bit but most lines look pretty straight and confident,

• ghosted planes:

most lines look good, one thing i do want to point out is that you could have taken more advantage of the space you had and fit the planes more snuggly, its not a mistake but you get to do more of the exercise https://drawabox.com/lesson/1/15/example (the example homework demonstrates this nicely)

• tables of ellipses:

just want to point out that you could have used a ruler for the frame if you wanted to (although i do see that you have done that for the later frame exercises) some ellipses look uneven and dont seem to be touching anything but thats to be expected at the start, make sure to take alot of time to ghost and practice them in your warm-ups moving on (can't really tell if you've improved or not since the pages aren't numbered)

• funnels:

once again you could have used a ruler and something round for the funnels themselves if you wanted to

most ellipses look fairly aligned to the minor axis

• plotted perspective:

looks good, just make sure that the hatching lines touch the edges of each box

• rough perspective:

the line quality takes a hit, make sure to take time preparing your line when ghosting

• rotated boxes:

some boxes arent actually rotating, the ones at the very edges/corners, instead they're following the exact same vanishing points, https://drawabox.com/lesson/1/rotatedboxes/notrotating

• organic perspective:

the convergence is shallow and thats good

but i can only find 1 page linked in your homework of the 2 assigned
