If you take your lattice, put the pic in the first window, and put a simple gradient in the second window, you can make the leaf bend. The link is an example of this, and you can exaggerate that bend a bit if you tweak it. At the link is a leaf I did last year from a scanned leaf. I used several lattices to get it where I wanted it though. I've also seen people export lattices to Poser, apply a magnet and export back to Bryce again.
