Nice and dramatic. Beautiful women. Maybe if the middle sister were a tad straighter and the chair back obscured. That might have also kept her left foot off the edge. It might have been nice to have had a red accent, perhaps red nail polish.
My nits are,
- the chair looks out of context with the other wood items, the chair back is too prominent.
- crop to a 4 x 5 constraint and it looks better, too much head room.
- sister on the chair, face turned to camera would be more flattering.
For post I'd add vignette on a layer mask and brush any away that touches the faces, just enough to darken the edges.
Man I agree these ladies put the Kardashians to shame. Nice job, not being critical kinda hard to take a bad picture with those ladies and I like composition.
