Can someone please mark my 8 mark structure question for English Language, thanks!

The beginning of the text focuses our attention on Rosie's new life, as we see her adjusting to her new home as 'she gazes vaguely at the sunlit overgrown garden'. The relatively slow pace of the text at the beginning could perhaps reflect how she is slowly adjusting to her new home life, which perhaps creates an element of relief for Rosie as it gives her a 'moment of calm'. We see a shift in the tone of the text when the other child is introduced which Rosie sees in the 'unfamiliar garden'. The writer utilises the sudden appearance of the child to create an element of mystery about the garden. This is compounded by a long description of the garden which is an 'overgrown mess' and a 'muddle of trees and shrubs'. Despite the pace remaining the same, a sense of foreboding is created about the garden, as we as the reader see its ominous nature. At the end of the text, there is a shift in the atmosphere which juxtaposes the earlier hopeful atmosphere. An element of mystery is created about the girl when she is described as being 'pale and drawn with anxiety'. The final line, which is written as a single isolated sentence, creates an element of suspense as the child is 'gone'. This perhaps shows how unfulfilled Rosie feels, which could also reflect onto the reader, as we never learn who the child was.
