That's a great idea about the wips, thank you!
After this happened I've decided to always charge new clients 100% up front. Though I really prefer to meet commissioners in the middle, so I'll keep sending out sketches first to people I've worked with before.
Definitely do keep an eye out, their second account was made at the exact time they ghosted me the first time, so chances are there's a new one on Fa already with another deer character.
