Warping in Illustrator on iPad

I'd love to be able to warp a shape in Illustrator (on the iPad).

For example, it wold be great to draw petals of a flower individually, warp each a little like they do in real life, maybe fold them over, then assemble into a flower

I think the multiple-gradient option might look more natural and 3d if done this way

If the shape has grouped lines, like veins in a leaf, these would probably look more natural if drawn first then warped.
