Don't know, if it's your best (since I'm new here), but it sure looks great... Though, I think it's too bright to be a wall... A "Piece of art" heading would suit this one better, IMHO... Good Job!.. BTW: Blink 182 Rocks!.. :]
hmm, im not a big fan of the smudge/dissolve/grunge effect but it seem good here, because it's kind of subtle. something seems to be missing though, the text is your weak point in some of your walls - try to work on them, they are too simple.
keep it up
