Wow, I really like the positioning of the characters in this. The colors go perfectly with the design itself; I really like the ones you picked, they don't blend in or stand out too much. I'm a big fan of vector shapes and rather like the ones you picked, but they do look a little bit bunched together and crowded together in one place where they're right next to the characters. The font you chose is perfect, and while I really like the color of the text, I'm not completely sure about the positioning? The diagonal rotation for the "soul eater" text doesn't look like it's the same as the rest of the lines/text, which makes it stand out a little more than it should. Maybe moving the "nice guys" text to the right and putting the "soul eater" text in the same font/style next to it would look more appealing, or splitting them to where they were next to each other, the same size, and divided perfectly between the diagonal lines?

This wall is very aesthetically appealing. :)
