Hey there! I'm so sorry about that! Dealing with lost character files is the worst.
I scoured my current laptop for the file and unfortunately it seems like I drew that on my old computer that died before I could transfer all the art over to this one. Granted, my files are currently poorly sorted so I'll keep an eye out and let you know if I somehow missed it. Thank you for reaching out and I'm sorry I couldn't help.
Hope you're having a nice day as well!
