beautiful color and use of natural light.
3. I like but the dad is a little too far back, looks like a floating head, I would like to have seen more of his body. Might have worked better if you had switched the girl in front with the long blonde hair and the boy standing in front of dad.
4. I like a lot, only thing is the kid with his arm on dad, his white arm agianst the black shirt totally draws my focus away from the group.
Nice work!
