Love 'em all -- even the giant spiders. Here's a hint I got from facebook SD group I'm in last night: adding "adorable eyes" close to the start of your prompt gives very nice eyes and fewer facial train wrecks. Works with both humans and animals. Had great results in 5 out of every 6 renders I tested so you might wanna try it out.

Tried doing a vampire bunny of my own. I think SD must have been smoking something funny, 4 out of 6 were way more vamp than ebil wabbit.

And from my "the day after Halloween" prompt:

Those two were done using the midjourneyart style model for Stable Diffusion. Same prompt in regular SD 1.5 was rather meh, artistically speaking.
