I noticed that you’re using Wonderboard but didn’t use a waterproofing membrane over the Wonderboard. The install looks nice but that shower will leak eventually...especially by that last piece of bullnose you installed. Sorry to be harsh.
It could have liquid membrane painted on under the tile, this is clearly a remodel and if the owner didn't want the entire wall redone that's what it is
Tile Baseboard should be the width of each floor tile, not overlapping. It would look nicer if you did that. Sorry to be harsh but that’s how I see all the pros do it. Unless it’s wood baseboard that runs the whole length of each wall
It's the customers preference actually and most people (from my experience) request the baseboard to overlap in a pattern to the floor tile, not come right up to the width of the tile.
Sorry to be harsh but you would have gotten a more professional look had you used HARD spacers. Soft spacers are uneven and amateurish to say the least.
I've done tile jobs with those spacers and the finished job looked great and the customer was super happy with the result. Yeah the hard spacers are better but using the soft ones isn't going to drop your end result down or look unprofessional. If you do the job right then that's what matters and it will look professional!
