Thanks for taking your time to critiquing my work. Here's the revision that I just did for ghosted lines . https://imgur.com/a/5TicWVd

I think this is the best I can do with my current level and as you can see the wobbling still exist. I took your advice to draw faster and tried to reduce the amount of pressure that I put on my pen just so that I can get that smooth line for the longer lines (some of them are still wobbly though). I also did notice that my line quality is improving after redoing this exercise although very slight .

Edit : Forgot to mention this but how do I go about adding a lineweight for the overlapping boxes on organic perspective? Do I just ghost the overlapping lines again or can I use a ruler for this?
