You don't need AI for interesting ads inSL. At all. There's such neat stuff you can do just with lighting. This was barely retouched, just a fix on some clipping of the sleeve due to the pose, and the motion blur overlay (which was subtle since there's already depth of field).
i don't find AI ads interesting at all, it's soulless. i appreciate ads like yours so much - lovely leggings by the way! 
Gorgeous
Pretty! AI ads are so fake and look so common.
That looks fabulous!
I have such an instinctual mistrust of AI that it makes me not trust anyone who uses it in their SL ads, to be quite frank. Your image here is lovely ♥
