it still makes mistakes at odd angles
an open palm or fist is usually fine
a "cute" hand pose with the fingers splayed is also good, but when the fingers start to occlude each other like picrel it tends to forget to draw the visible knuckles for the occluded fingers and starts blending them together instead. stuff like holding a cigarette or a pencil still seems to give it trouble.
i usually throw "4 fingers 1 thumb" in the prompt but it's not entirely foolproof.
