I need help!!!

I am building a new house and am picking out the paint (attached is the floor plan and my selections). I was able to choose 5 colors and have chosen the following for each of the rooms:

SW7104 Cotton White - All Trim & Closets

SW7640 Fawn Brindle - Foyer, Great Room, Upper Hall, Mud Room, & Master Bath

SW7032 Warm Stone - Dining/Morning Room, Kitchen, Study, Bedroom #3

SW7676 Paper Lantern - Powder Room, Bedroom #2, & Main Bath

SW6471 Hazel (Turquoise) - Master Bedroom, Laundry

I would love to hear peoples feedback on where they would put the colors. For instance - is fawn brindle to dark, too light, just right? Is Hazel too much, should I go with a more neutral tone? Should I paint the main areas on the 1st floor the same color? So many questions and my head is spinning. Choosing everything out prior to this was easy but i think the paint selection is going to be the demise of me...well either this or lighting which i have just started looking into!

I have been in search of a foyer light...were going to have a 2 story foyer...and I have no idea how big it should be or how low it should hang. I wish i had a designer to do all this.
