Mini Photo Shoot

I am not a photographer. I always get these really good ideas and then get frustrated when they don't turn out the way I pictured them in my head. I was pleased with four of the however many pictures I took of Ms M. We decided the black and white were cuter. Which picture do you like best? 

a)

b)

c)

or

d)

RB likes c the best and I think I'm leaning toward a. Hope you enjoy!
