Thanks, Antonio! I am glad you liked it
I think part of the feel you described is also from the fact that I put a lot of emphasis on the eyes (my wife thinks too much actually) by sharpening and brightening the eyes.
I like your suggestions, so much that I am going to give you the original raw file and give you permission to process it the way you have in mind and post it back here so that I can TFPH, how about that?
So here is the DNG file:

And as for the fever, you were very close. He was asleep in the bed and woke up from the sound and light of my flash, so looks like he is hot from fever, where actually he was hot from sleeping under the blanket. Good guess
TFCH!
