I like 1, this is my favourite type of mono, not sure about the position of her head as you can't really see her face, perhaps looking a little higher.
2 doesn't really work for me, although as a recent dad I understand the idea!
3 I love, is this a real reflection or photoshop trickery, either way it works for me!
Nice set and I really like the lighting and mood. The reflection works really well, but the only thing for me, the reflection looks too sharp and distracts my eye from the main image, Maybe a little softening or reduce the exposure of the background reflection a smidge
i like them its something personal to you..
