Portrait ideas

I'm doing two portraits of some adorable girls. Just figuring out the composition.

two 10x13s (matted in 14x18 frames)
--> Portrait style

-->Gesture style

Wish I could get a better angle of Ari (on right) perhaps looking up, but I really love the gesture of Anne as she looks at her rock. If I did this pose, I would use the expression on Ari's face below.

Or, one 11x14 drawing in a 16x20 frame
