I’ve got bad news for you. The beautiful baby that you gave birth to, loved, and nurtured, has grown into a monster. It must be stopped, and only YOU can stop it. I am of course speaking about the picture book that you’re working on, specifically the beautiful chrome car bumper you just drew, or the building facade that took you 5 hours to ink, or the cherry blossom tree that you spent 2 days painting (how can you mess up a tree, right?). Well, you’ve been missing the big picture. Literally. Take a nice step back and look at your entire composition. You see it now, don’t you? That bumper is actually not supposed to be shaped that way. The turret that you painstakingly drew each shingle on is out of perspective! And that cherry blossom tree is somehow crooked (but it’s a TREE!). I can see you mouthing that involuntary expletive. Go ahead, let it out, because this is going to suck. You are going to have to kill your baby.

Geez man, let it GO!
I know what you’re thinking, “SCREW YOU, MAN! This is the best bumper I’ve ever drawn!” I hear you, because I just drew the best bumper I’ve ever drawn, and it was not shaped the way it is in real life (let’s blame the tricky chrome reflections in my reference!). But guess what? That crazed automobile collector who is going to buy my book because they know every minute detail about ’54 Chevys IS going to see that the bumper is inaccurate, and she WILL email me to complain about it (and maybe even give it a menacing review). AND, that’s on ME. If I’m making a book about cars, and I blatantly disregard the details that are going to make car enthusiasts swoon, then I’m not doing my job, and I’ve lost my credibility.

the bumper in question–I also forgot the keyhole!!!
It’s not just about being technically accurate. You could be working in a completely abstract style that excuses you from lots of formal “art rules.” The fact remains: if there is something in your composition that is calling too much attention to itself in a way that has nothing to do with the plot, you’ve just pulled your reader out of the story! This is the LAST thing you want to happen. No bumper is that precious.

This can be applied to writing, illustrating, and all other creative endeavors.
Don’t cry yet. Do the job first, mourn later. It will be easier for both of you this way. You’ll erase the best bumper you’ve ever drawn, but you’ll save the rest of the drawing you’ve made. Plus, you just proved you can draw an amazing bumper, so why can’t you draw it again? Your drawing is going to be stronger because of this.
Who knew erasers could look so threatening? Pick it up. Erase the bumper. Draw a better one.
Here’s a gentle reminder, friends: It’s probably not THE best drawing or painting EVER made in the HISTORY of Art, right? If you put it next to the Mona Lisa, would she turn to look at it and be all, “OH, DAYUMN!” I didn’t think so.
Take heart. Your baby will return, maybe not specifically as a car bumper, but as a really amazing overall piece that you can be proud of!
