Well, heres a few little ideas for textual features:
Use of personal pronouns such as "I", "me" etc. This helps to engage the reader and create a personal tone.
Story is told in first person, in this way, the narator takes the reader into her confidence so the reader can journey along too. It is in this way that Francesca's journey to self-discovery, is revealed to us.
Characterization of William Trombal acts as a catalyst for Francesca's inner journey.
Use of dialogue
Told in the present tense.
Anyways, hope that helps a little!
