I actually think it looks very pretty. I can not tell if it is grouted yet but if the grout hasn't been done yet, maybe pick a darker color to have some contrast. I would't change the tile, keep in mind you have to put your small kitchen appliances on the counter and you can add some nice kitchen accessories for interest. Right now it looks like a lot of tile... because the counters are empty. (IMO of course)

I love my backpainted glass backsplash. Very simple and clean and beautiful!

You could go with a more patterned tile but since this is all installed I would suggest doing some great items to sit on the counter. That will add decoration and your personality .

A WOW backsplash would be too much with a WOW countertop.

I think the countertop is the wow. It's beautiful!

You chose well. Beautiful choice. I agree with Tatts. No contrasting grout.

Agree with all those reassuring you that your backsplash was a lovely choice. Your countertop is an attention getter. Your lovely cabinets have a lot of rectangular pattern in both their door style and placement. That is softened nicely by the counter but I think a curved or patterned tile backsplash would be vertigo inducing between them.

For that reason, I also agree with matching grout. Your tiles have enough of a wave that you don't need grout to accentuate them.

When the appliances are in and it's a working kitchen, I hope you love it. You did good!

You know, I had one other thought. Don't know honestly if this is nuts, but you could try going up one more row of tile on the wall to the right and see how it looks.

Hang in there as is. No contrasting grout. Your tile ads just the right amount of interesting texture. If you wait until all the appliances are in, add some good sized art on the right wall over that tile & then pull a color from that art into the accessaries. Think you'll be quite happy with what you have.

I'll add my name to the list of commenters who are encouraging you to stay the course. Let the countertops be the stars of the show. Your backsplash has texture. That will be quite enough when everything else is together. Nice job!

Echoing the above comments that you already have a Wow in your kitchen, and it's your counters.

The backsplash you chose is perfect for it, and please don't use darker grout. We used a handmade-look tile in similar dimension and color as well, and grouted as close to the tile color as possible - it's already got enough going on with the texture/irregularity, and dark grout is going to distract from that (plus draw your eye to the grout, rather than your overall kitchen and those counters).

I like it. Use very similar groutcolor

It looks great. Mid project self doubt is inevitable for non pros. Trust yourself. You done good.

I like your tile. I think the only thing I would have done differently was to pick up the gray/green color in the counter and do the backsplash in that color instead, but that's because I'm tired of white kitchens with white backsplashes. It's all personal preference.

Like others, I love your backsplash. Have you thought about taking it to the ceiling on that little wall with no upper cab?
