it's a trial/error thing, but good ones are medium breast (for shape), collarbone, arms up, choker (generally the spicy-sounding ones)
when it goes too apeshit, you can course-correct by changing the pose with i.e. closeup or cowboy shot, upper body to zoom out a little
chibi can be used to affect age, lowering comic tends to give nicer results
:D and ^_^ can fix the face, arms can be fixed by reducing hair length and removing hats
animation stuff is below the editor, so run that. save the poses in the editor and then put them in the list, then generate. you'll have to find a way to make webms out of the mp4 output though, I just use ffmpeg.
protip: you can use duration_sec to affect the length and mp4_fps can be upped to 60, though it'll take proportionally longer to render
