Nothing wrong with your pics at all, Shas. And those shower shots are nothing short of spectacular!
But if you really want to look less pink, there's an easy trick you can use to give yourself an instant all-over tan. Use a tungsten/incandescent light (ie normal house-hold lighting) as your primary light source and drape a tissue over the flash of your camera when taking the shot. The whole shot takes on an orange/yellow colour cast and gives more colour to the results. Fold the tissue over more times to pronounce the effect more.
Take a look at my profile pics for an example - I'm probably as pale (if not moreso) than you, but I used that trick for those shots.
