The copper metal tiles are beautiful and they go really well with the center of the back splash and your counter tops. Whichever tiles you go with, this will be a gorgeous back splash!

Gorgeous tile. Will the copper change color over time, or are they somehow treated to stay true? I think the landscape tiles might get 'lost' in the multicolored subways instead of being a focal point. My non-pro opinion.

Love the copper tiles on there own, wouldn't add the artwork, sorry

I agree copper tile no art work and FYI that style of some different tile behind the stove IMO is a very dated look.

Thanks everyone for your replies. I appreciate the input. I'm going to go with the copper because I see your point about the art tile getting lost in the colored field tile.
Regarding the granite and letting it shine. .... There are several other countertop areas where the granite can shine by itself. This will be behind my cooktop so I want something more decorative there.
As far as it looking dated. .....I Hope it looks dated. .... my house is a 1920s arts and crafts. These tiles are from a company that specializes in arts and craft art tiles. I hope they look like they belong in a house from that era!! I don't think any quality tile work ever looks "dated" ..... You can see châteaux in France from the 1500s and 1600s that have tile work in the kitchen ....... and every era since ...... so I have to say I don't agree on dated. What I Think will look dated in a few years are the millions of tiny rectangular glass tile back splashes everyone is using these days. .. that all the pros recommend. So I'm OK if this looks "dated".
Thanks for your help everyone!

The Motawi tiles are gorgeous and will be perfect for a 1920s house. My only question is the granite selection may read too "new".
