Tiling, is this "good enough" from a pro?

So, after spending month's of weekends redoing my bathroom, I got a tiler in to stick the tiles on the brand new, dead plumb, wedi-boarded walls. I think he has underquoted and therefore rushed some key details. Am I being too fussy?

Pic 1 shows how the level of the mosaic tiles is 2-3mm below the level of the wall tiles. They seem to be fairly "in and out" along the whole length of the wall, but right at the end they sink below the finished tile level leaving a wobbly grout line where it hurts up to the painted wall.

Pic 2 shows the opposite wall, where the mosaic run ends 10mm short of the painted wall, and the three tiles above it are all cut crooked. I presume he plans to fill these gaps with grout.

So, good enough for a pro? He has had 3 days at this 2m X 2m bathroom, 750 quid for labour. Not done yet. It would have taken me three times as long but I would have kept redoing it as required until it looked right! I am worried that now it's set any rectification work may damage my carefully laid (and quite expensive!) watertight boards.

The problem is that those edges will be seen, there are no tiles going onto the white wall. If he had started from that end and worked backwards then he could have lost any errors with an overlap at the other end.

I wasn't fussed about how much I paid, but this was the only guy I could find that didn't have a 3mth waiting list...starting to see why!
