When you have an idea in mind for a skill that didn't happen to be in Disco Elysium, but you feel like it would *fit* -- you can describe it to me. Recieve a few (usually three) concepts, settle for one of them, and get an artwork akin to Signature Skill, but with the skill of our collaborative design. If you don't have a *description* but posess a general idea -- it's fine as well, that's what concept art is about. We can go with that.
In general...
I need a statement of description or idea
I draw 3 concepts (or a few more if needed)
We settle for one of them
I draw Signature Skill with the chosen design.
