The head is kinda iffy and the way the tail connects to the torso is pretty thin as well as the tail itself.
“Humanoid snake” those are usually called lamia.
Oh and the color scheme is really dull for a snake, very poisonous animals usually have bright colors to signify their danger to predators.
Need better photo’s, too focused on random pieces to get the general sense of what is what. I think i can tell a tail and arms, and potentially a head Necormorph style face… but its a bit jumbled.
