lovely eyes!
I find the building in the back somewhat distracting. Its a dark structure that offsets the bright skin tones, pink dress, and flowers. Not sure if a flash was used but I like the twinkle captured in her eyes. The best part was the single flower just in front. I don't see the strap as something that takes away from this picture.
I too like the first better. The best part of the subject is her wonderful eyes.
