Studio Renovation // Help me choose!

I need your help! There's a small nook in my studio... I've mentioned it before. We were going to turn it into a pretty little reading nook. But the more I thought about the functionality of that space within my art studio, the more I thought about how PERFECT it would be to install a sink! I could use it to wash my printing blocks, brayers, my hands, brushes, plates... I would get a lot of use out of it. 

Here's the space, all freshly painted (and without a light fixture)...

So... along with the weird nook came a weird space that used to be a window. Prior to the renovation, it was covered with some kind of thin board that was made to look like brick... YUCK. So, we put up drywall there, and I would just love to put a beautiful piece of wallpaper over the drywall in that space. 

It would be the only place in the studio that has a real pop of color, and with it being such a bright, cheery spot already, some fun pattern there would be great. 

And, so you know what the sink will look like... Here's my inspiration for that.

Which wallpaper should I use? I can't decide!
