In my previous home, both Andy Warhol and pop pieces were all over the place, starting in the dining room. The pink Natalie Portman painting is by a Warhol-inspired artist named Ronnie Bauttista.
Great use of a small wall space. I like the vivid contrast of the (v. bold) art against the black walls. I also like the accents: the white giraffe, chairs and hanging light fixture all stand out nicely and the white I'd the background artwork also accents these pieces. I also like the bright pink and green in the room, especially the green of the chair and carpet, since they coordinate nicely with the green 'P' in the piece of art that hangs I'm the top right corner if the picture
I love these prints/paintings - I want something like this for my own house. It's been some time since I picked up a paint-brush, much preferring pencil-art myself, but the way of drawing with the paintbrush as though it was a marker... does something for me.
The black wall in combination with these heavily lined pieces makes the look very clean and cool.
