Some bg suggestions here.
Maria singing bg is the best one for goldenslaughterer. And for the executioner, first bg is pretty good. Second pic would look awkward for a piece like the executioner. Some additions: http://puu.sh/49ikq.jpg http://puu.sh/49iBl.jpg
liberatedliberater: This piece plays during ErikaxBeatrice duel at BattlerxErika's wedding, so this pic would look nice http://puu.sh/49kBG.jpeg if not, try using some Bernkastel pics i posted for the executioner.
resurrectedreplayer: http://puu.sh/49j5X.jpg (would be better without the text but well, still fits) if not, try finding some sorcerer Battler pics.
death: http://puu.sh/49ja5.jpg Best pic for this piece, totally from the real scene
dreamenddischarger: Actually Natteke's map has the best bg for this one, but using the same picture would be awkward. Soo how about this: http://puu.sh/49jC3.jpg
worldenddominator: http://puu.sh/49jPh.jpg (basically Natteke-map's bg but the parent lol), http://puu.sh/49jPZ.jpg
lastendconductor: http://puu.sh/49kc8.jpg, sadly this is pretty small even though it is from the actual scene http://puu.sh/49kcL.png
