Your floor looks perfect. My floor was just poured last Friday, and they did an awesome job on it, very smooth and flat. There is some variation/whiteness from that bit of creme at the surface the I am thinking would look better if it was blended in or removed. I know that it would go away in time with weathering/washing - do you think that it has changed any from the time it was poured just with people working on it and routine cleaning?
considering a light acid wash before sealing when the time comes ? Luckily I have some additional concrete that I an use to test things out on.
Your finished look is just right IMO.
