I dunno, I think it's a fairly good likeness of Leah. As for the question on Esme Frost, in my story they're the bastard half-sisters of Emma. Her father Winston nailed his secretary, and nine months later the Stepford Cuckoos popped out.
I'm more surprised that you didn't ? at the Hardy-Frost bit. O_O
Although I think all of your pics have been great, and this is still really good, I feel that this is the weakest so far. There's something about the girl on the right (Esme Frost?), her face doesn't seem quite right. Don't take offence, cos your still an amazing artist!
