Two Seated Poses - Together or Apart?

These two seated poses are from a recent Open Life session -- painted on a 16"h x 20"w piece of loose oil-primed linen.  I'm currently deciding on whether to keep them together - cropped as shown as a 14"h x 18"w piece -- or  broken into two separate paintings at 12"h x 9"w each.  Option two of separate paintings is shown below. What do you think?
