I don't do intros anymore, but I'll see if I can help.
On the whole I'd say this is pretty darn good - you've introduced the novel's main ideas and what you're going to talk about in a general sense. However a few things- you've mentioned the techniques Woolf uses and what they demonstrate, but I think you can expand on this. Take this part: "repression in a post war society can cause both silent suffering, yet a greater appreciation for life"- this is great stuff but for an introduction you could make it a lot punchier! The suffering experienced by characters isn't just that, it's this relentless despair to the point of considering death;on the other hand, their appreciation of life is at times utterly ecstatic. So i guess what i'm saying is use stronger language and extend your ideas

For example, you haven't explained how or why post war society represses these emotions- you could fix this by making an overarching comment eg: how the structure of society dehumanizes the individual. Then again I could be reading too much into this; it's only your introduction, after all. :p
Just nitpicking: don't put a semicolon in the last sentence. Either split up your ideas into separate sentences or use a comma. I wouldn't use"we" either, though I'm only suggesting this because I was told to avoid it. Use "the audience" or " the reader" instead.
