Oh, those art was supposed to be a joke, but i'm genuinely honored that you got inspired by it haha! XD I'm actually one of fan artists that's still pretty active in TNMN fandom, specifically on Tumblr.
Unfortunately, i can't reveal my art account fully here, but if you want to see more of my art, you can go to Tumblr and search through TNMN tags, if you see a person that mainly draws Dr. Afton fanart or you find some of his fanart with "yc" watermark on Google, that's me! ;)
Good luck with your art journey btw!! :D
