Actually getting the light right is the hardest part IMHO.
I see you adjusted your lighting/WB... it looks like you set your white point on your primary layer? This can overdo the white, I've done that myself. For better results, you may try creating a layer & setting your white-point on it. Then adjust your opacity to less than 100% & see how you like the results.
Of course getting the lighting right isn't easy, but once you figure that out you're golden. If you got all the light you can get in a situation, go for a higher ISO setting. The slower shutter speed should make better use of your available light.
I'm figuring out stuff as I go too, so hope this helps. They are very good pics!
