To be honest it wasn't really quickly done (a few hours here and there on a few days), I'd like to be able to work faster than I do right now but for the moment I'm still sharpening my skills.
If you're interested by these creatures the best you can get is still Lovecraft's novel "the shadow over Innsmouth", the text that invented them. You can see plenty of them in most Lovecraft inspired video games and in movies like "Cold Skin" or Guillermo Del Toro's "the shape of water" (kinda ... even if it's not said clearly, but Del Toro is a fan of Lovecraft).
Ho and by the way, one of them fucks a girl in Alan Moore's "Neonomicon".
COMMERCIAL BREAK: There's also one of them eating someone alive in my book "le voyageur onirique" but unfortunately it's not translated for the moment (and won't be soon). Anyway, There's plenty material about them in pop culture, you should be able to find way more movies, games, comics, books etc... about them.
