Opinions Needed

I am slowly trying to update our living room. I can't do a full blown makeover all at once, so I'm taking it step by step. I want to make a collage wall, so I have been collecting some art prints. I have this lovely one from Colorbee, so I put it in a thrifted white frame. But the problem for me was the different whites. The paper is a bluish-white next to the frame. So I decided to repaint it.



So I painted it Aquatic Mist by Valspar. But now I'm not sure. My other option was Granny Smith by Glidden. The Granny Smith color is similar to the lighter green on the E in 'sweet'.

(This is how it looked previously.)

Here you can see it all together. What do you think? Would you leave it aqua or paint it green?

And do you have any suggestions for this shelf in general? I'm not lovin it...
