I like the composition Ian, + she sure does have a gorgeous face
I prefer the mono, but not keen on the selective colouring of the eyes.
The colour shot is good, except for the skin tones - red + blotchy with distracting vein detail. I get this with my little one as well (3 yrs old). What I do to avoid this is have a special set of settings I use just when I photograph her:
Soft focus filter
Colour mode on camera set to Ia (softer, less vibrant colours)
Tone compensation (contrast) adjusted to low contrast
Saturation set to medium-low
I'm sure your camera has different setting parameters, but you get the idea of how to soften skin tones in-camera
