two things - First, I'm not sure I like that muted color. Sorry, just my opinion of course (and it's your room so only you and the wife needed to like it anyway). A lot will depend on if you're using crown molding and what color that will be though. I find that white strip there now very distracting. See my thoughts about color in the next paragraph.
The other thing, I like the accent lights you have in the soffit. Very nice effect. Would you be willing to share what type, size, and wattage they are? Where did you pick them up? I am embarking on (planning) my own project and I would like to do something similar. Okay, back to the color. As great as PS it leaves a lot to be desired for choosing color in the real world. I once painted a ceiling a color that looked great in PS but what happened in the real world was very different. That color reflected downwards and shifted the color of the rest of room including the wall color that I liked previously. I was not a nice effect. Anyway, notice how much the color changes on your walls where it is lit by those cans vs in the shadowed area and non direct light area. It can make the same color coming out of the can look like a different color. Have you thought about going monochromatic and using the wall color on the ceiling? With those accent lights on the walls they will look lighter than the ceiling does simply because of the lighting. Obviously it will match well too because it will all just be varied shades and brigtnesses of the same color. Depending on how often those lights will be on and what other ones will be used it can change quite a bit. Anyway, just a thought.
