I honestly like all three of them and think they'd all work fine with the backsplash. The rugs by themselves I like the first one best. I think the way to be sure it works with the splash is to pick something of a larger scale. So... for that reason my pick is the last one. Very pretty kitchen!

i like the first one best and the third one a close second
it depends on the other decor in your home .......i think.....

I like the last one the best because of its more free flowing form. You already have the more geometric patterns in your backsplash, and I'm not feeling the zebra.
However, i probably would pick something with a little bit of color or maybe black and white.

I prefer the 3rd...

Last one!

Here are some mockups.

Next one

third one

I am leaning towards the second or third I posted. Can't go wrong with any of them. Hope this helps.

I like the last one too. Love your kitchen!

I like the 2nd and 3rd one.
