>>21595457It's in the right path, but you must note something: if you're going to erase, then you must carefully erase it all. Even if it means zooming it 10000% to erase a cell, it's better than leaving erasing marks around; it makes the art ugly.
A brotip: copy a few transparent cells and then proceed to paste it over whatever you want to erase. It's way faster that way, so it'll save you some time, and you won't risk erasing what you don't want to.
