You are so right on that score! However, take a look at the following for black and white abstract art similar to the above. And, etsy has several vendors that will make the listing of city names like the one above for California. Good luck!

It might be better to post photos of your walls and see if people can come up with recommendations for you.

I specialize in large artwork and my work is listed here: https://www.etsy.com/shop/ShoaGallery

You can find many other good artists online. Art is very personal and you really need to like what you get.

Good luck! :)

I agree looks like arendering why not get what you like instead of copying someone else . Find the ones that you think look good together print them off and play around with them you can get a feel for the sizes from the inspiration pic and adapt to your space.
