Everyone who has done art has run into the problem of making mistakes and usually those mistakes warrant starting the entire art piece over or fixing the area it happened in. But sometimes, those mistakes turn out to be pretty good and you keep them in the end. As Bob Ross would say "We don't make mistakes, just happy little accidents". Does this happen to you often? Do you prefer to keep okay looking mistakes or would you rather redo them to make them perfect? I tend to make mistakes. Pretty often. Normally I'd go and fix them but sometimes I'm too lazy and just keep them. And the way I see it, most people won't even notice the tiny little mistakes.
I tend to make lots of small mistakes, but I usually use them as ways to improve the piece which always turns them into happy little accidents. If I can't rework the piece (which is rare) I start from scratch with the old piece in front of me to remind me what to avoid doing.
I still make a lot of mistakes but I can still see I've improved since I started drawing more. The most common mistake I make is continuing on the wrong layer, had to redo half a piece because of it.
I make a lot of mistakes; generally I undo them, Bob Ross would be very disappointed. Sometimes I just go with them though, and I end up reworking the piece into something that would have turned out better than my initial idea anyway.
