Turquoise is my favorite applicance color, so needless to say I love your GE kitchen! The wall mount refrigerator is just about the neatest refrigerator ever.
I would explore the new beam system below the floor at bit, though. The beam itself looks pretty beefy - it's hard to tell scale but perhaps a 6 x 12? - but it's being held up by only two 2x studs from what I can tell. Normally you'd open the adjacent walls up and put posts in them and make sure the sole plates are on footings, rather than just put the studs on the outside of the wall finish. So long as the 2x studs are on footings you're probably OK.
