The small looks much better on you (can see even better in the second set of pics) and has a much nicer shape.
I briefly owned the large baby,and looking at your piccies I am happy that i returned her.
The small baby cabas is still a big bag, but not so huge that it'll be totally over when the over-oversized bag trend fades,KWIM? I actually cannot think of any circumstance in which one might need a bag as huge as that large cabas. It's not even practical as luggage,since it doesn't really close.
Sorry if I sound vehement; I'm still bitter and twisted since I waitlisted for 4 months to get the smaller baby cabas and then the larger one showed up on my doorstep...
Enjoy that wee bag!!
