I'm trying to decide on ordering some prints to do either 3 or 6 grid of frames in dining room/kitchen area

I thinking of whether to:

1. buy one of these sets
http://www.etsy.com/listing/110936544/set-of-3-abstract-art-landscapes-minimal?ref=shop_home_active

http://www.etsy.com/listing/128079139/set-of-3-minimal-posters-abstract?ref=shop_home_active

2. pick three completely different color scheme prints from the shop in #1

3. do a mix of 3-6 completely different prints (one from each shop), something like this..

THANKS!
