This or That?

I've been wanting to upgrade my art collection for some time. I have a few wonderful original pieces, but also plenty of mass-market prints in Target frames. I like them, but it's (way past) time for something a little more grown up.

West Elm has several works that caught my eye, and a couple of them would look great in my office:

The office is black, white and gray with touches of pink, so either one would work beautifully. The abstract is on sale and would be more versatile, but I'm really drawn to the flamingo. It just makes me smile.

Any thoughts?
