Yea, what Marla said. My first though was, coming from the deck of the house your eye would catch the back of the lounge chairs on the sun shelf instead of the open pool. I don't know much about pools, but in reading on here, dreaming of my future in ground pool, several people have mentioned too many waterfalls can be overly noisy. Looks like you have quite a few, so may want to keep noise level in mind. I would go with curves or straight lines, but not both, maybe just the curve on the back wall with the falls. The seating around the pool deck looks spread out and not much room for more than two or 3 people in one place. Depending on how you plan to use your pool, that may be fine or not. With this set up, you really don't get to take advantage of the covered patio you already have to sit in the shade and watch people in the pool, especially if you have kids. Whatever you decide, I'm sure it will be beautiful and you will love it!
