Take a look at the sentence again:
In a home, Wesley wants windows showcasing the skyline of Los Angeles, steel
and glass furniture sparkling in the sunlight, and __________.
The blank requires a noun phrase modified with a participle phrase. You chose a sleeping Great Dane on the white shag carpeting, which is a noun phrase followed by a prepositional phrase. You thus have a parallelism error. Before you continue, review the rules for parallel structure.
