This is the entirety of our conversation together, including a smaller screencap for the latest message due to the fuzzy date format.
Then here's the proof that I paid her on June 20, 2019:
At this point I have no confidence that she will ever get back to me, or that I will receive my art. She either straight-up ignores you or gives you the run-around. I know $30 doesn't seem like a lot of money, but I still paid for a service I'll likely never get. Also note that she changes her username a lot, and has her read receipts turned off on Twitter.
Goes without saying, but I can't recommend purchasing from her.
