I have seen this type of walls at an artist but the characters were original too and they always surprised me because of their simplicity and the really nice combination of colors:red,white and black always do the trick.It's the second wall from the artist that I see in this type,I liked the one with Nana where I haven't seen the series but I have most of it(I have to get the rest too) and I like this one too because I really like Yukari and the wall is really simple and yet very attractive,it captures the eye!
