So I was skimming through Google image search's results for img163.exs.cx/img163/5174/ange…, and I saw a poem right here on dA that had this image...and credited it to `MPsai. I decided to file through her gallery. No dice. So I skimmed what the Wayback Machine had on her. Still nothing. So I decided to contact her personally on the matter.
To my surprise, she said yes the same day.
So thank you, ~KitKat44 and `MPsai, for helping me close another case
