Today's horrible artwork 😅😅😅

For this I did sketch it out and digitally color but I've run into trouble for shading. If it isn't clear ( cause who could really tell from how bad it's draw it's supposed to be a " horror scene " of a " murder " that's just a misunderstanding from the person being unconscious and the jam looking like blood ( school project thing that's weird ) anyways is there any way to try and shade the scene to make it seem like a dark ominous and how should I texture the jam? bit of a weird question but a necessary one thanks for all your help and support and I hope that you do respond to the QOTD ( question of the day ) in the other post of today :3
