With the Magnetic lasso tool, I selected the bushes and thing next to the man's right shoulder, and placed the selection on its own layer (CTRL+J).
With the same tool I selected the man's head, placed it on its own layer
With the same tool I selected the red patch of hair at the bottom, placed it on its own layer
Going back to the layer with bushes, I opened a Hue/saturation adjustment layer above it, and clipped these two layers (CTRL+G).The dialog for the hue/sat layer has a box to colorize; checked that. Worked the sliders to colorize to suit
Next I went to the layer with the man's head, same procedure - adjustment layer, clipping, colorize
Next I went to layer with the hair, but did not check "colorize" --adjustment layer, clipping, but just worked the lightness slider
At this stage I set my foreground color chip to ligfht blue --C7D7EA
I created a stamp visible layer, a layer that combines all the layers, yet does not flatten. To do that, open a blank layer at the top of the stack, and press CTRL+SHIFT+ALT+E)
I opened a photofilter adjustment layer at the top, used Cooling #82 with luminosity checked.
Merged down to combine these 2 layers
I shut off the visibility of all the layers below the stamp visible layer, and on this layer I selected the blown out sky with the magic wand tool, then hit delete on the keyboard. Used the eraser tool to remove a few yellow spots.
Got the Paintbucked tool out of the toolbox and filled the sky area with the light blue color
Added a few clouds and a frame.
