#help with source

Help me find this drawing's artist!! Hello! I don't use tumblr much so i apologize for any mistakes in my formatting. I also don't know if this is the right place to post this but i don't really know of any other place i could do this in since i asked in a few places already lmao Long story short: a good few years ago a friend gifted me this OC, the only detail he said about her was that her name was "The DeathBlossom", and that he had more drawings of her. Sadly my friend just sort of disappeared after this and i wasn't able to reconnect. I know he wasn't the artist...and that's about it. I'm hoping anyone can point me in the direction of an artist for proper sourcing (and to find those missing drawings that have been gnawing at my mind for years...) because this character has grown quite a lot on me over the years and i'd really like to know her full story as more of a closure thing than anything. (Just in case, yes i used reverse google image search, tineye, saucenao etc. but i either suck at using them or i couldn't find anything...)
