If it's a thing that your brain considers "boring" or "same as always", you will skip it mentally and visually. Drawing a lot does that to you, one wrong fingers isn't even that horrible, when you start looking into other problems, like two left feet, crooked bodies and shit like that. You have to either actively remind yourself to do better or get good enough to never make a mistake. Even then, all good artists know small tricks to keep the quality in check, the famous "flip the picture to see mistakes" comes to mind.
