Good on the glue down. You are sure you want a wood floor that close to what looks like a kitchen there? One busted pipe, and you get to replace that you know. The glue down ones aren't quite as bad, but they don't take getting wet well at all. They aren't like the old solid board hardwood floor you used to see anymore. It is oak, but it is oak plywood now, not solid board, and when it gets wet, it will buckle. Today's hardwood flooring is really only suited for livingroom, hallway, and bedroom use. Even the old good stuff didn't last well anywhere it can get flooded.
All of that aside though, First, the floor will be no better than the subfloor it is laid on. Even the smallest pieces must be swept up before laying the floor down. A grain of sand becomes a hump after a few months of walking. Any cracks in the slab must have crack weld applied, and ground back flat. Any cracks left unfixed will pull the floor apart as soon as the seasons change. Stager the joints as much as you possibly can, and where you have all the small pieces on one end, they also need to be staggered from one side of the room to the other. All of those small pieces on one wall will stick out like a sore thumb. You should go back and forth starting on the opposite wall with each run. It is no ameature job really, but it can be done if you take your time. When you think that the joint is tight enough, smack it one more time for good measure lol. Do ALL of your cutting outside, it's a lot of walking, but one small missed piece of something gets covered into the glue, and it will show up soon.
If it were me, i would return the wood, and do a real nice tile floor that would last forever instead. I love wood floors, but i have seen some real heartbreaking messes when i used to do constuction work. With the glue down, the damage will be only near the actual water line, but those floating ones are sitting on a huge sponge, and they can buckle to where you can't even walk across them quick if they get a flood.
