On the one hand,
Gigantic curvaceous thighs, breasts you could sink not just your hand but your entire body into and girlie-cum you could drink by the pint. Not sure where one would want to insert oneself though; I suspect at that scale the nostrils would be too big and the tear-ducts too small.
On the other hand,
Tsundere alien loli. I shan't bother even attempting an acceptable description here, it's a damned tsundere alien loli. Let your imaginations run wild.
On the other other hand (Possibly foot, if you're dexterous enough,)
WHICH FORM CAN SING BETTER? Do I choose the undoubtedly deeper, slower, richer song of the giantess, sung in a delicious contralto and coupled with the resounding echo characteristic of all Zendrati, or do I aim my ears at the sweet, innocent dulcet tones of the loli? If I hear that she's going to sing about a boy, I shall put myself on the waiting list for a nutbladder transplant.
