1> Horizontal. Why? It makes absolutely zero sense to frame them this way.
3>The group's eye lines all point to different locations. My money is on "somebody trying to help" with the baby's expression, and distracting the infant, who appears to be amused by one of the other family members standing behind you to your left. The bald, white sky in the upper left is very distracting: a solid, entirely landscape background would have made this photo nicer, I think.
4> Seems kind of far-away-looking, and the camera height seems too high. I do not like the horizon line running through the heads of the back people. The far-away-looking thing looks to me to be from a relatively short focal length that is giving a LOT of depth of field, all the way back to the modern, wire fence line in the back right. I'd loved to have seen this shot with a 180mm or 300mm from farther back, with the backdrop "suppressed" more. JUst seems framed awfully loosely, and with more depth of field than optimal to put the emphasis on the people.
5> The baby, with an entirely landscape backdrop...I wish shot #4 above had been handled the same way, without the bald white sky. In this photo, of the baby, there are only two main planes: near, and far. With #4 there is near, far, and Infinity, three planes of distance. Pretty serviceable shot. BIG baby, framed just right.
6> Suitably demure, the young maiden is posed well, and her expression is excellent. Solid shot. Posed better than her brother in #2, whose sword is sort of sticking to the side of his head, and who is "lost" by being seated right on his butt in the grass, even though there's a suitable log nearby, thus losing a lot of the charm of his costuming.
As a set, 1,2,4,5 have really,really,really outrageously saturated greens, that probably will print out of gamut. Shot #3 has rich,verdant, and yet believable green grass colors. It would be nice if the greens matched, since they are such a huge part of most of these shots. Skin tone rendering is excellent in ALL shots.
