Experimenting on Photoshop - Changing the tones of my images

Original Image: 

Black and white:

Adding a 'blue' tone to the image:

Orange tint: 

All though the original is a more natural tone which you could say works best for the theme I'm doing. I wanted to experiment with changing the colours/tones ever so slightly. I wanted to make the images bolder and more attractive. With images like these - based on everyday - they can appear to be quite bland, normal, boring. So with changing the tones, I wanted to see if I could make them more attractive and interesting. I would say the black and white one doesn't work, due to the nature of the work I want to take. It takes away the 'natural' element of them- changing them to black and white gives this type of image a fake and set up element, making you think that the image was set up. Also, people often tend to view black and white images as more emotive. I don't want people to force themselves to have to find an emotional meaning behind my images (just because it's in black and white) if there is a meaning, I want them to naturally find it themselves. 

My favourite of the three would definitely be the 'Blue' one. Her skin colour still appears to be a normal natural colour - unlike the orange toned image- and despite the background being a less natural colour. I feel that this all works together. The image is more eye catching and interesting.
