I'm in the process of having my 30 year old IG gunite pool mildly renovated with an Aquabright surface and new waterline tile, plus a few other odds and ends. Today while I was at work they installed the new waterline tile. I got to see it this evening when I got home, and I'm pretty unhappy with the workmanship. I was hoping I could post a few pictures and get opinions whether I'm being too demanding or this really is unacceptable, or maybe some of each for different areas. Also, it's helps to vent.
In general, the spacing between tiles is all over the place. Sometimes it's too big, sometimes it's too small, sometimes it's non-existent. For example:

While I'm not happy with any of the spacing in this picture, I'm especially worried about the tiles that are jammed right up against each other. They did this a lot. It doesn't seem like it'll be possible to grout between them, which will result in water getting behind the tiles. Also, shouldn't the two planes at the corner of the skimmer be aligned to form a clean turn? I'd think it would be possible to do so by varying the thickness of the mortar bed behind the tiles.
This second photo is an example of where I go back and forth about whether I'm being too picky or not. It's just poorly aligned tiles, it won't cause any water issues. But would someone who was taking their time and focusing on doing a good job really have misaligned the tiles this badly? Waterline tile is decorative - the whole point is for it to look good, right? If it looks like garbage what's the point? Counterpoint - I'm being too nitpicky.

Here's the other skimmer. Is that gap between planes really normal/acceptable? Can grout securely span that distance, especially around a bend? Also, that horizontal tile at the bottom right is about 1/8" higher than its neighbor, with a bunch of empty space beneath it. That one definitely needs to be re-set.

Thanks for letting me vent, and please let me know if and where I'm nitpicking stuff that is just normal variation.
