First of all, credits to the Hakufu Sonsaku vector by DragonBlade & elfe-noire43.
I put up a very simple wall. Chose a texture for the bg that was similar to an alley brick wall and repainted it in some places. Then color balanced it to match the scan. Later on applied a few filters and linear light duplicates with different fill and opacity layers. The dragon was a little hard to blend to the wall and to give it some personality without taking focus off Hakufu but I think I managed it. I'm not too keen on the font I used, but I haven't found a better one. I'm looking for the title in kanjis too, so If anyone knows were I can find it, plz comment and tell me so. Thx!
