I like the composition, but, I'm not sure if I'm fond of the sepia tone. Egg hunts, Easter, speak colors, which is lost here. Otherwise, I like the shot.
I like the execution, but her expression seems awkward to me. Would have really liked the same image caught with a different look, a smile, reflective look.
Sepia tone here, IMO, is a little too strong for the wistful nature of the photo. The warmth is good, but it's fighting too much with the playful nature of the photo, wanting to give it a darker, more antiquish feel which I don't much care for.
