I'm the family cook and I had to look away from that. Really brutalThat cut on her hand was brutal.
about upscaled, it seems a bit too thin i think? maybe you can try to up the contrast a bit first then upscale it.
my usual quality check is just to look at the art in different range (range of you-monitor or img scale-monitor in %) and this one seems too thin that it make the lines barely visible when the original are kinda visible
