>>630782Yeah, you got it.
For stuff like this I would probably have sth like this:
Final Line Art Layer
Messy Line Art Layer I lowered the opacity on after I was done to draw over it
Optional Older Messy Line Art Layers that had even messier lines
Optional Colour Layer(s)
Duplicate of Original Picture Layer I directly edit/erase the breasts on
Original Picture Layer (hidden) that I keep in case I mess up with the editing of the duplicate
I often duplicate more layers than necessary and sometimes add blank ones on accident so I usually end up with a lot of layers lol
There is no one right way to do it tho, just do whatever works best for you
