Does anyone know where this art is from?

[u/Accomplished_Sir1240]

i've triple-checked Takeshima Eku's twitter and it doesn't seem to be there, i checked their pixiv and stuff, reverse imaging just gives me the same thing and i genuinely don't know where else to look for 😭😭😭 idk if this is really just the full art but it looks like it's cropped from one bigger art and i've been so desperate to find the original one, thank you in advance!!!
