Your word "decorates" is not appropriate here. I think you mean "modifies".
The quotation seems to be from here:
Blogspot "art articles"
[Francis Wey] suggested that they [photographs] would lead to greater naturalness in the graphic depiction of anatomy, clothing, likeness, expression, and landscape configuration.
The word "naturalness" is followed by a preposition phrase that contains another preposition phrase:
[in the graphic depiction [of anatomy, clothing, likeness, expression and landscape configuration]].
The first preposition phrase has the preposition "in" followed by the noun phrase "the graphic depiction", which has a specifier, an adjective, and a noun.
The second preposition phrase has the preposition "of" followed by a series of nouns. That second phrase modifies "graphic depiction".
The combination of the two preposition phrases modifies "naturalness".
So, it is definitely possible for a noun to be modified by a phrase, which is in turn modified by another phrase.
