This picture frame collage is neat. I love the font on the wall and I adore the famed initial in the middle. This would take up a good chunk of our huge living room wall so my wall won't look so naked.
What makes it work: I like that this one wraps a corner. This gallery wall reads as quite simple, almost minimal, thanks to nearly identical frames, and very similar color schemes amongst the art: either in black and white, or warm/pinkish tones.
