Tile in kid's bathroom

We began our first tile job in the kid's shower area. We used inexpensive snow white 6" tile. The walls were fairly straight and square, but now I know I would hate to get into remodel jobs on my first attempt.
We put in a 16"X16" recessed shelf for shampoo and cut tiles to put a diamond design using 1" blue glass tiles in one row. This definitely added time and complexity to the job, but it is turning out nicely. We even had Mr. Vector show up fresh from a tile class he took on Saturday morning. Everyone helped place at least 1 tile. Helps spread the blame around.
