HELLO

Seems like your ghosted lines aren't straight and either didn't reach the mark it should be or over the mark it should be.

I wish you could practice it everytime before you start a section as warmup.You have to be very confident when the ntp of your pen touches the paper and do a quick (slightly faster) single stroke line with moving only your shoulder.But instead of doing ghosted lines I want you practice it as doing Planes , they are same but planes are just slightly complicated.

Ellipses looking clean but for the funnel part those ellipses all have the same degree the middle one is facing you by its side so it's 0 degree but as it turns you can see slightly bit around like 10 degree and so on ... 25 40... and it gets more and more facing towards you btw ellipses are looking good tho

boxes are bit weird tho but no worries in next section you'll be drawing 250 boxes so it'll get better in no time :D
