I really love this - what a beautiful moment you've captured here! The pallet is so soft and dreamlike, and you've done some wonderful posing. I absolutely adore the tulle ruffle on the leopard's tush, and naturally the tails - great work!
My major complaint is that the roses on the trellis don't convince me they're roses at all. They look more like spanish moss hanging down than actual plants, so that's kind of "eh, but danjiii~iiii" for me, but I'm a plant nut (I probably couldn't have told you that was a leopard except I read a comment naming her species XD;;;;;;;;;; ), so ... take it with a grain, yeah?
On the whole, though, I think this is great - lighting, posing, colors - you've done a great job.
Very beautiful, though I can't help but feel that the colour balance should have been shifted more towards the warm end. The use of cool colours feels a bit eerie and unsettling given the original premise.
