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.
Line: The book shelf in the room shows the use of line because the book shelf shelves are built against the wall forming a miniature tree. Our eyes are drawn to look at the book shelf tree from bottom to top and outward to the tree/bookshelf branches.
