I hope you're not considering changing your backsplash for the tile sample you have leaning against it. That style of thin irregular horizontal mosaic is too dated now to put in your kitchen. I also find the grey too cold to go with your countertop which has more warm tones in it.

I'm going to recommend a colour from C2 Paint's "The Naturals Color Collection by Barry Dixon". These are full-spectrum paints whose quality is unsurpassed by any other North American paint. According to what was shown at last September's London Design Week, greys are shifting to be more natural, and away from the cool black/white blends. With your counter and cabinetry I'd recommend BD-13 TROUGH GREY for a warm complex tone that's right up to date.

I looked for an image to show you the colour, but when I googled it, some very different tones showed up. I'm attaching one of Barry Dixon's matching fabrics in TROUGH GREY which shows the colour very well.

jmcdane, the look we've moved to, and which I think is pretty classic, is using one tile repeated across the space. It can be as small as a mosaic, either square or rectangular or round, and can be as large as an oversized subway tile. The difference is that it's not a collection of random sizes or broken up by accent tiles. The look is a continuous cohesive look across the backsplash area with no part that stands out more than another. See the photos below for ideas.
