Hello, Frank. I think your White Balance is still a little bit off. Here is my suggestion for you:
1. Copy the background layer.
2. Apply your first level adjustment layer. Set the values of the RGB input data to:
R= 0, 1.15, 255
G = no change
B= 0, 0.66, 255 This will set your middle gray adjustment.
3. Apply another level adjustment layer and adjust the RGB input values to:
R = 9, 1.03, 251
G= 5, 1.02, 253
B = no change. This will set your adjustment on the black and white levels.
4. At the top most layer, combine all layers by pressing CTRL+ALT+SHIFT+E. This new layer will apply the two level adjustment layers into one combined layer.
5. Using this new combined layer, you could use my vivid light detail enhancer tutorial to add extra detail on the image.
6. Adjust the contrast by applying a very mild S-curve to add contrast to the image.
7. Darken the top background a little bit to increase perceived depth on the image.
8. Apply a little vignette to center the attention of the viewers to your kid.
9. Sharpen the image.
Here is the sample of the output when all the recommended adjustments are made:

Hope this could be of help. Good luck my friend.
