Since I love trying to solve a puzzle I was trying to figure out the source of post #9817146 so I could upload the original art. A lot of immediate reverse image results linked the above image to the artist peargor (who seems to have made this personification design) but then I found it was uploaded and sourced on e621 attributed to the artist "Mutahard123" sourcing to an upload on R34 from that user. They state that it is a recreation of old fan art that had since been deleted. Someone replies and states its a remake of art by weatherRW, but trying to find that account only leads to a dead twitter another user claims this R34 is the original.

I didn't think there was any smoking gun that proved that weatherRW was the original artist until I found this Reddit thread reposting the R34 link attributed to Mutahard123 and in the comments someone asks about the "original artist" only for someone to mention he still exists and @ his new twitter account which causes them to reply with their Reddit account Wezaen114p which draws almost nothing but Plants Vs. Zombies art and states they never gave permission for someone to use their "horrible drawing."

Probably more to dig up, still not confident in the assessment that the topless one linked is the original art since there isn't enough proof, but I'm fairly convinced Weather at least made the art this is based on.
