Niiiice work here. You have a very creepy aethstetic and atmosphere, and it makes it super fun to look at. Nice imagery. The scratchy and scribbly lines and use of black and red add a lot, and it seems like you have some real passion behind it. Some criticisms: I'd make the colors a bit duller (slide the color slider a bit more towards gray). It'd REALLY complete the look, in my opinion. There are lots of good dark colors here, but some areas pop with colors that feel a litttle too saturated. Also, little details like animating some slight hair movement can add a lot. When the girl sits up in bed, it might have been a nice touch to make her hair sway a bit when she stops. I understand the style is sketchy and simple, but it can never hurt.
I liked the very brief and simple last frames. Good job, and keep at it.
