to me, the first and third have DOF issues. I think you either needed a little more DOF to bring just a tad more INTO focus, or focus more on the belly and lower hand and go with less DOF since the other hand already has focus issues. (IE, on #3 the shawl behind her is OOF, and her right hand is very soft focus, but the shawl in front and her left hand are in focus) I don't think the B&W conversions work for these. its all dark. there's nothing that gives much of any contrast to the black.
The posing on #1 is good, minus some stray hairs. (i might have gotten the hair away from her eyes)
#2 appears to be a candid shot,
#3 looks kind of like a color crop of #1. again, I don't like the DOF in this one. but the pose is good.
im surprised you dont have a more frontal shot showcasing that henna art. #2 is the closest, but the artwork competes for attention, and is partially obscured by the child.
