What do you do when your brain refuses to imagine the character right?

I'm generally ok with forming an image of a character but it doesn't take much to get blown off course by the most inane descriptions or even random fan casts.

I had trouble in Villains and Virtues where my vision of Amma drifted to look like an ex best friend, all because of a particular way a curl of hair was described in passing. Honestly it was horrible and I had to spend 20 minutes gazing at pictures of Dove Cameron like that one wolverine meme to fix it.

And today I saw the author of Cities of Smoke and Starlight, bless her beautiful soul, post a very Henry Cavill edit of her rascally young screwup MMC (whom I adore) and I had to go into damage control about it. Love Henry Cavill, but I beg, can we not have every single MMC face claim him? The men already have a hard enough time not being boring, the sameface is Not Helping 😭

Sometimes I wish I would just draw them but then I'd have to stop reading to spend a few hours doing that
