One of my favourite things to see in a model portrait is a strong confident look. Unfortunately I've seen some people take it a bit far and it can look too much, almost arrogant.... thats not good.
I love Moralinda's subtle confidence here. The smile just says it all.
I guess why would she not be confident. Shes a talented model with a stunning look. She also happens to be an incredibly nice girl too so it was hung hanging out during the shoot.
