So, is the girl a really tall Little Person, or just kind of short? In the first appearance, Val is shoulder high to Alan and chin high to the guy with the clip-on nose, which assuming they're of average height, indicates that she's probably slightly under 5 feet tall. Then she can't see over a bar which is hip-high to the woman behind it. Either it's a 5 foot tall bar with a ramp or a gigantic barmaid working behind it, or for some reason Val is now 3 feet tall, which would mean that Alan and Nose are also quite short. We see that Alan is about half a head taller than Francis, though that could just be perspective - they seem about equal in the first frame, but Francis is shorter (though he is hunched) in the other frames, so we know that Alan isn't particularly short. When the group is sitting at the table, Val is up to about nose-high on Alan and Nose, until Skull walks by. Then she either stands on her chair or jumps on the table, to grab Nose by the shirt, gets off the table to walk past Alan, then apparently crouches to turn back to Nose, since now her head is barely above the tabletop, seeming to have shrunk several inches between frames. Seriously, in frame 3 we see that at the tabletop (assuming that the frame bottom is at tabletop level) is below her bust, probably right around waist-high. In frame 4, only her head and shoulders are over that level.
Her repeated insistence that she is a dwarf and the proportions Kurtz is using - the stocky, squarish build - would seem to hint at being a Little Person, though obviously she's ACTUALLY going to be a Fantasy Realm Dwarf like Binwin or Gimli, SURPRISE. Given her wildly inconsistent height, it's kind of hard to tell.
