Innocent Expression → Childishly Pouting

Let's see... how about we play with that expression a bit? I don't think innocence is appropriate for someone flashing her ass to me, but I'm not quite sure what to do instead. I suppose if we keep the "innocence" theme... Let's try something like 'Childishly Pouting.'

The hallway's end rushes toward us, only to stop just in front of Arma. The plaster over the walls peels away to reveal smooth bricks, and light shines through the passage just ahead once more. As for Arma...

...her ass is still clearly visible, although she's got some kind of hot pink underwear riding up its crack. Red sleeves have filled in the gaps under her shoulder-guards, and her skirt is now entirely steel and fused to her armor. She's also standing much closer, and the armor of her legs flares out widely as it approaches her thighs.

...she also looks kind of comically grumpy, with a very pronounced frown and furrowed brows.

Mission accomplished, I guess? Now... where in the world do I go from here?
