I have to say, IMHO, that that leo is a one of a kind animal.
It's kind of like hitting the lottery or breeding 2 random,normal leos and hatching out albinos, without any idea that they were het for albino.
You could line breed that girl and really pull out those nice, bright, wavy orange stripes.
If I were you, I'd email Matt and Susan at HQReptiles (they're nice people - though I've never met them in person) and ask them what they think of her.
Once again, that's a great looking (and healthy looking!) leo.

PS: Whatever you do, don't give her away!
