on the meaning level, i can't make out much of a content. it's a rather direct depiction of the joss stick holder. the cross processing added an interesting colour layer but it does not seem to enrich the subject. there does seem to be some attempt at trying to depict a rather secretive and dark atmosphere, but that did not go beyond an attempt and remains very much just an effect.
