Also, she's not as good. Sure, there's a bit of potential, but I've worked with countless girls like this, pretty with a resemblance to a great, but it usually takes so much to get a shot from them that's comparable to whoever they're being compared to, you're better of spending time on someone with a truly unique look and a natural ability to come alive on camera. So yeah, Nikole does look like Gemma in the last shot, but she doesn't have that magic that made Gemma so special. You can't teach, or imitate that, you either have it, or you don't.
That last picture! Wow, what an uncanny resemblance. It'll be interesting to see the quality of her work. Looking similar to Gemma might help at first, but she needs to prove that she can produce good work. I wasn't particularly wowed by any of her photos, but no doubt, she'll improve.
