How does she looks "scary" as a model? No scarier than any other model out there. I'm surprised she hits the ball as solidly as she does - I think it's great to be strong and not look it, better than the other way around. Of course, I would like to see Dani look a little more "healthy," like an athlete. If you got it, flaunt it. But, please Dani, you got talent, flaunt that too. Best of luck in RG!
If Dani wanted to model, I don't see why she wouldn't be cut out for it. I mean, most models are not conventionally gorgeous: they are exotic, strange or plain unattractive. Dani's face is conventionally more beautiful than most successful working models out there. She does appear quite thin in these pictures, but in modeling, there is no concept of "too thin."
Makeup, if done right, could never make anyone looks *worse*. If it does, then that's the makeup artists screw-up, not the person's.
