My first wall of Peace Maker Kurogane, my idea of the wall was i wanted to make it look like it was on the back of a coat or something
apart of clothing and so on, it ended up pretty complex but found it looked better more simple, oh by the way "ONI" means demon, like in the anime when Tetsu asked Hijikata "make me into a demon" is where the title came from,

how did i make the wall you ask well firstly i got the scan and cleaned in up in illustrator which gave it a more paint effect, then i overlayed a texture over the wall, i believe the texture is denim which i changed the colour to more browny tint, further more i add a little shinsengumi tag on the tab, and the signature shinsengumi uniform pattern (haori as they call them) the moutain peaks, plus some little blood splatter, cant be without some blood i always say, anyhooo im boring you to tears by now so thats it for now, good day to you ya hear! *shakes fist* ^^
