I love the hugging one even if they aren't looking. I am a big fan of non-"perfect" photos. It seems like a good representation of them. I like the one of them all looking up because they are all looking directly at the camera even if not smiling. Or that same picture  is another option of the twins besides the one under the tree. I should be able to get Nolan out of the one of them looking up at me. Then, I put two trio options.  I think they all need to be different photos since (i.e. not the two peeking from the tree and then J smiling...looks odd to have two the same and one different. You could do separate prints and frame/matte them next to each other or have them printed as a trio. They are probably best in black and white because they are different backgrounds/etc. Also, if you choose the one of them on the bench, I would suggest black and white.
