Your boxes are incredibly messy, with every single line on every single box you must use the ghosting method from lesson 1, In addition, if you miss a mark adding more lines to "correct" it will only make it stand out more and make it harder to see your mistake. If you make a mistake leave it alone. How are you supposed to improve and move on from a mistake if you can't see it?

This is difficult! This will take a long time, but it will improve your skills a lot.

If you have the determination to do this once I'm sure you have the determination to go back and do it properly.

Goodluck!
