Hunting art

If you have ever been to my shop you will have seen listings like my Diamond felt coaster which is displayed on my great white, blank wall. Until recently I was very fond this wide emptiness cause it gives our busy household something clean, minimalist, uncluttered space. But now, I don't know if it is the nesting instinct of a pregnant lady... well, I WANT ART on my wall.
Something bright, abstract and BIG!

So I have been hunting the net, Pinterest and various blogs and I think I have narrowed it down to these ones (found on society6.com) :

...which gets me thinking... maybe I should create my own? Ahhhhh, the joys of indecisive pregnancy hormones.
