Good points, I'll be doing some tweaking to the model. The look like she's "crawled into daddy's space-suit" is kind of what I'm going for - it's not her suit, so it's a little to bulky. That said, the arms could probably do with some thickening to make them a bit more in-proportion with the rest of her.
And the face - well, yes, she does have a black eye, and a cut on her forehead (which seems to be slightly obscured by the hair, so I could tilt the head back slightly to reveal that more) but this is going to be more obvious in the portrait view for speech.
Nice critique though, so I'll get round to incorporating those into the figure.
