My avatar is normally tiny. This is because the human is small too -- I'm part Asian, so what I think of as a normal-sized human is usually about 2/3 the size of a westerner. That means that I'm not sure what constitutes a 'large' avatar. This fine challenge helped me think through it. To me, 'big' indicates more than spare. Saddlebags, tummy fat, lovehandles, boobs -- I upped all those sliders until my girl looked like she had some extra. Then, I made her tall and tough! I still don't know if this qualifies as big -- I always have to adjust prims down to size for my normal avvie, and this girl doesn't have to adjust much at all...
I'm trying to maintain Acha-style, however, so the big girl gets to be fey.
