Always feel confident to question your tiler. Big tiles like these are easy to lay and to line up. If you are not happy then tell them. You are the customer and your satisfaction should be paramount. It looks as though the surface isn't flat. Is this the case? Or is it the tiles that make it look this way? If it is the tiles, tell them. Even if they can't fix it without costing you much more $$$, they may be able to offer you credit for future works.
