Looks like you have a great subject here! For me the lighting on the face is way too harsh and I am not sure I like the orientation. Maybe this would have been better with the girl in portrait format rather than horizontal? :o)
This is cute. Lighting seems a little harsh making the photo seem a little flat (lacking depth in contrast). JMO of course. :) Good luck in the challenge.
This is such a cute gal! I like the pose and expression, too. You may want to experiment with adding some contrast, or fiddling with your mid-tone levels to add some richness to the shot. Good luck!
heavy lipstick on such fresh beauty is disturbing. I think I would have had this upside down ie. head pointing to the bottom. The sideways composition is neither here nor there. Maybe also a tighter crop off the chest area...dunno just my opinion.
