All depends on the sight lines, floor levels, personal taste. I always check options with clients, it's can be a surprise what delights one eye offends another. In your example pic the floor level is different in the shower so you may have a whole tile at floor level outside the shower and cut inside, some people would want a whole tile at floor level inside the shower. Unless the walls are newly built your bigger problem will be how straight they are. Victorian walls often slope in at the corners and top of walls because plasterers tended not to smooth out the plaster so much in those areas. If you get an 8ft straight edge and run it all over the walls it will give you an idea of any problem areas.
When tiles are big it's harder to even out problems with the walls. On the other hand mosaics are the hardest tiles to work with and probably best left to someone with experience. Luckily they're out of fashion at the moment.
Forgot to mention to always use a notched adhesive spreader and keep the adhesive clean of any lumps or debris.
