NO. A busy busy mismatch disaster in the making. They are unrelated in any way.

For the best look in a bath? No more than two tiles. Pick something you can use on the floor, and REPEAT it on the shower walls. Pick the shower floor to coordinate.

Or pick the floor, and choose something very complementary in color, scale for shower.

Pick WHICH of the two tiles you've shown, and you will get help here.

And, just a reminder, not all tiles are suitable for use on the floor!

A "walls only" tile can't go the floor, but

a FLOOR tile can go on a wall!!!!

Walls only are designated as such.

Yes!

In your inspiration picture, the floor tile has black in it and the accent wall in the shower is black. If you want to use blue instead you need to choose a different floor tile. There are similar floor tiles that have a blue background instead of black. Or go with a white/off white.

Why not pick a palette??? It's a sky ..........

I like the second photo Jan posted, i.e. having one feature wall the same as the floor tile, then find a white tile that matches the color of the white background as your field tile. If you prefer blue as your main accent color, you could choose a tile something like this:
