Your art itself is cute, but it is telling a horror story so I think it works.
Cute drawings can work very well with horror because it is typically a good juxtaposition b/c it typically gives a sense of comfort like puppies while horror fills you with dread.
I do admit it does get tired after a while for your art to be commented cute when that wasn't your goal for a drawing, so on that boat . . . you're not alone.
