This is a good question. In general I tend to keep my grim fantasies kind of tame. If that can even be said given the nature of this kind of work. 

Normally the kinds of things I’ve thought of include anything with gun fire, stabbing, accidental deaths, innocent bystander, blunt force trama, drowning, and hanging just to name a few. 

Most of the time, my grim-dark fantasies are only applied to certain characters for certain situations. For example, I have a couple of anthro characters that I will only place in certain grim situations, as any other situation I can apply them to don’t really seem necessary. For example, one character might seem more likely to be in a situation where they can drown rather than just happening to be in a situation where they get shot by someone. 

It all depends on how tasteful it is really. Again an odd thing to say given the nature of the work, but what I draw in a grim setting has to make sense. 

FoE characters getting shot, hanged, or anything that seems feasible in that universe is a easy possibility for me to draw, and seems more than likely to happen. I’ve gotten requests before where the situation given didn’t seem to be realistic enough for me to draw, and I won’t do it purely out of that mindset. A character being killed just for the sake of being killed isn’t something I can enjoy drawing, purely because there needs to be a reason for that untimely situation to happen in the first place.

It also should be noted that I don’t tend to do anything that involves bodily fluids that isn’t blood, and I don’t normally like to draw organs or guts. That kind of thing isn’t what I’m into. I’m a bit more into the rag doll like effect that the characters can have when being subdued or placed in a deceased status. 

Hope this answers the question. Any other more specific questions just let me know. I’d be happy to answer them.
