@algoatall I mostly fill myself up on projects so I can keep busy because I'm pretty bad at coming up with scenes on the spot.
But if I am forced to come up with something (e.g. for a daily draw) I'll usually revert to drawing one of my OCs or think of a random bg pony, usually just posing cutely or in the bababa animated style.
Posing / scenario can be a whole other can of worms but often choosing a character first leads into me thinking about scenarios I might like to see them in.
