So, if you've been following immortaltom on patreon (I think he posted them on DA as well) - you may have seen these pics he did for me. His normal tier for a one-char pic is $25/month for a pic every month - I worked out an arrangement for significantly more than that in order to work on a 2 char. set of concept pics.
No process per se, but some fun little pics. You may or may not like the wordplay :)
