You know what's fun? Doing self-indulgent bullhicky about your characters. Something I love to do that's a bit tumblry is mood boards. Milanote
is a great service for it, it supports gifs, images, videos, etc. Great stuff. Be sure to put stuff that's not just an aesthetic choice that look
like your character, but just stuff that inspires you and feels right. Here's a link to mine that's fully media-supported: https://app.milanote.com/1KPXJ415dZB3eH?p=dQHornqS01N
(Note, I made this without the intention of sharing it, so the link has one artful NSFW video in it, which is censored below)
And an image:
Straightening into rigid, militant attention, A division of Bloodlochian soldiers squares its shoulders and crisply salutes you.
